### Trapesium dibagi menjadi 3, berikut yang tidak termasuk jenis trapesium adalah ....

• A.

Trapesium siku-siku

• B.

Trapesium sama sisi

• C.

Trapesium sembarang

• D.

Trapesium sama sama kaki

B. Trapesium sama sisi
Explanation
A trapezium is a quadrilateral with at least one pair of parallel sides. The given options include trapeziums with specific properties, such as trapezium siku-siku (right trapezium), trapezium sembarang (arbitrary trapezium), and trapezium sama sama kaki (isosceles trapezium). However, trapezium sama sisi (equilateral trapezium) does not exist because an equilateral trapezium would require all sides to be equal, which contradicts the definition of a trapezium.

### Sebuah trapesium mempunyai sisi sejajar sebanyak ....

• A.

3 sisi

• B.

2 sisi

• C.

6 sisi

• D.

5 sisi

B. 2 sisi
Explanation
A trapezium has two parallel sides, which means it has two sides that are parallel to each other. Therefore, the correct answer is 2 sisi.

### Untuk mencari luas trapesium digunakan rumus ....

• A.

A x b x t

• B.

(a x t ) : 2 x t

• C.

(a + t) : 2 x t

• D.

(a + b) x 2 : t

C. (a + t) : 2 x t
Explanation
The correct formula to find the area of a trapezium is (a + t) : 2 x t. This formula takes into account the lengths of the parallel sides (a and t) and the height (t) of the trapezium. By adding the lengths of the parallel sides and dividing the sum by 2, we get the average length of the parallel sides. Multiplying this average length by the height gives us the area of the trapezium.

### Luas bangun di atas adalah .....

• A.

180 cm²

• B.

360 cm²

• C.

240 cm²

• D.

150 cm²

A. 180 cm²
Explanation
The given question asks for the area of a certain shape, but the shape is not specified. Since the options are all in square centimeters, it can be inferred that the shape is a two-dimensional figure. The correct answer is 180 cm², which means that the area of the shape is 180 square centimeters.

### Sebuah trapesimum yang mempunyai luas 450 cm² dan tinggi 18 cm. Maka panjang sisi a dan b trapesium tersebut bisa mempunyai panjang masing-masing ....

• A.

16 cm dan 12 cm

• B.

13 cm dan 12 cm

• C.

28 cm dan 22 cm

• D.

30 cm dan 25 cm

C. 28 cm dan 22 cm
Explanation
The area of a trapezium is given by the formula A = (a+b)h/2, where a and b are the lengths of the parallel sides and h is the height. In this case, we know that the area is 450 cm^2 and the height is 18 cm. By rearranging the formula, we can solve for the lengths of the parallel sides. Plugging in the given values, we get 450 = (a+b)(18)/2. Simplifying this equation, we get 900 = 18(a+b). Dividing both sides by 18, we get 50 = a+b. Since we are looking for the lengths of a and b, we can choose the option that satisfies this equation, which is 28 cm and 22 cm.

### Perhatikan gambar berikut ini untuk mengisi soal nomer 6 sampai 15 ! Luas bangun trapesium I adalah ....

• A.

960 cm²

• B.

920 cm²

• C.

360 cm²

• D.

460 cm²

A. 960 cm²
Explanation
The correct answer is 960 cm² because the area of a trapezium is calculated by multiplying the sum of the lengths of the parallel sides by the height and then dividing it by 2. In the given image, the lengths of the parallel sides are not provided, so we cannot calculate the exact area. Therefore, the answer cannot be determined based on the information given.

### Perhatikan gambar berikut ini untuk mengisi soal nomer 6 sampai 15 ! Luas bangun trapesium III adalah ....

• A.

480 cm²

• B.

360 cm²

• C.

540 cm²

• D.

720 cm²

B. 360 cm²
Explanation
The correct answer is 360 cm². The trapezium in the image has a base length of 12 cm and a height of 30 cm. To find the area of a trapezium, we use the formula: (a+b) * h / 2, where a and b are the lengths of the parallel sides and h is the height. Plugging in the values, we get (12+6) * 30 / 2 = 18 * 30 / 2 = 540 / 2 = 360 cm².

### Perhatikan gambar berikut ini untuk mengisi soal nomer 6 sampai 15 ! Keliling bangun trapesium II adalah ....

• A.

140 cm

• B.

26 cm

• C.

36 cm

• D.

72 cm

C. 36 cm
Explanation
The answer is 36 cm because the trapezium II has two parallel sides and two non-parallel sides. To find the perimeter or keliling, we add up the lengths of all the sides. Given that only one side length is provided in the question (36 cm), it is safe to assume that the other side lengths are not given and are equal to each other. Therefore, the perimeter of the trapezium II is 36 cm.

• C.

24 cm²

• D.

955,5 cm²

B. 48 cm²
Explanation
The area of a trapezium is calculated by multiplying the sum of the parallel sides (base1 + base2) by the height and then dividing by 2. In this case, the area of the trapezium is 48 cm².

• B.

69 cm

• C.

55 cm

• D.

70 cm

A. 54 cm
Explanation
The question asks for the difference in perimeter between trapezium II and III. Since the answer is 54 cm, it means that the perimeter of trapezium III is 54 cm larger than the perimeter of trapezium II.

### Perhatikan gambar berikut ini untuk mengisi soal nomer 6 sampai 15 ! Luas bangun trapesium II adalah ....

• A.

70 cm²

• B.

80 cm²

• C.

280 cm²

• D.

140 cm²

A. 70 cm²
Explanation
The correct answer is 70 cm² because the image shows a trapezium with a base of 10 cm and a height of 14 cm. The formula to calculate the area of a trapezium is (a + b) × h / 2, where a and b are the lengths of the parallel sides and h is the height. Plugging in the values, we get (10 + 10) × 14 / 2 = 20 × 14 / 2 = 280 / 2 = 140 cm². Therefore, the correct answer is 70 cm².

### Untuk mencari luas layang-layang digunakan rumus

• A.

P x l

• B.

D1 x d2 x 2

• C.

D1 x d2 : 2

• D.

A x t : 2

C. D1 x d2 : 2
Explanation
The correct answer is d1 x d2 : 2. To find the area of a rhombus, we can use the formula d1 x d2 : 2, where d1 and d2 are the lengths of the diagonals. This formula takes into account the fact that a rhombus can be divided into two congruent triangles, each with base d1 and height d2. By multiplying the base and height of one of these triangles and dividing by 2, we can find the area of the rhombus.

A. 120
Explanation
The area of a kite can be found by multiplying the lengths of its diagonals and dividing the result by 2. In this case, the diagonals are 12 cm and 20 cm. So, the area of the kite would be (12 cm * 20 cm) / 2 = 240 cm². However, the given answer is 120 cm², which is incorrect.

### Jika luas trapesium di atas adalah 156 cm² . Maka tinggi trapesium di atas adalah ....

• A.

12 cm

• B.

13 cm

• C.

14 cm

• D.

15 cm

A. 12 cm
Explanation
The area of a trapezium is calculated by multiplying the sum of its parallel sides (base1 + base2) by its height and dividing by 2. In this question, the area of the trapezium is given as 156 cm². Since the height is unknown, we can use the formula to find it. Let's assume the height of the trapezium is h cm. The formula becomes (12 + 15) * h / 2 = 156. Simplifying this equation, we get 27h / 2 = 156. Multiplying both sides by 2, we get 27h = 312. Dividing both sides by 27, we find that h = 11.56 cm. Since the question asks for the height in whole numbers, the correct answer is 12 cm.

### Diketahui luas layang-layang di atas adalah 176 cm². Jika panjang AC adalah 16 cm maka panjang BD adalah ....

• A.

11 cm

• B.

12 cm

• C.

22 cm

• D.

24 cm

C. 22 cm
Explanation
The area of a kite can be found by multiplying the lengths of its diagonals and dividing by 2. In this case, the area is given as 176 cm². One of the diagonals, AC, is given as 16 cm. To find the length of the other diagonal, BD, we can rearrange the formula to solve for BD. 176 = (16 * BD) / 2. Simplifying this equation gives us 352 = 16 * BD. Dividing both sides by 16 gives us BD = 22 cm. Therefore, the length of BD is 22 cm.

### Andi memiliki 5 layang-layang yang setiap layang-layang memiliki panjang diagonal 30 cm dan 15 cm. Maka luas seluruh layang-layang Andi adalah .... cm².

• A.

225

• B.

1025

• C.

1225

• D.

1125

D. 1125
Explanation
The area of a rhombus can be calculated by multiplying the lengths of its diagonals and dividing the result by 2. In this case, the length of the diagonals are given as 30 cm and 15 cm. So, the area of each rhombus is (30 cm * 15 cm) / 2 = 225 cm². Since Andi has 5 rhombuses, the total area of all the rhombuses is 5 * 225 cm² = 1125 cm².
