Correct Answer
A. 48 cm
Explanation
The correct answer is 48 cm. This can be determined by examining the image provided. The shape appears to be a rectangle, and the length of one side is labeled as 12 cm. Since a rectangle has two pairs of equal sides, we can assume that the other side is also 12 cm. The perimeter of a rectangle is calculated by adding up all the sides, so 12 + 12 + 12 + 12 = 48 cm.

Correct Answer
D. AB + BC + CA
Explanation
The correct answer is AB + BC + CA. The question asks for the formula to find the perimeter of a triangle. The perimeter of a triangle is the sum of the lengths of its three sides. Therefore, the formula AB + BC + CA correctly represents the calculation needed to find the perimeter of the given triangle.
16.
Rumus untuk mencari luas segitiga adalah ....
Correct Answer
B. Alas x tinggi
Explanation
The correct answer is "alas x tinggi". This is because the formula to find the area of a triangle is base multiplied by height. In this case, "alas" represents the base of the triangle and "tinggi" represents the height. Therefore, multiplying the base by the height will give us the correct formula to find the area of a triangle.

Jika sebuah segitiga mempunyai luas 200 cm² dan tingginya adalah 10 cm. Maka panjang alas segitiga tersebut adalah ....
Correct Answer
B. 40 cm
Explanation
The formula to calculate the area of a triangle is 1/2 * base * height. In this question, the area of the triangle is given as 200 cm^2 and the height is given as 10 cm. We can substitute these values into the formula to find the length of the base. 200 = 1/2 * base * 10. Simplifying this equation, we get 400 = base * 10. Dividing both sides by 10, we find that the length of the base is 40 cm.
25.
Keliling segitiga sama sisi adalah 78 cm. Maka panjang setiap sisinya adalah ....
Correct Answer
C. 26 cm
Explanation
The perimeter of an equilateral triangle is equal to the sum of the lengths of its three sides. In this case, the perimeter is given as 78 cm. Since an equilateral triangle has three equal sides, we can divide the perimeter by 3 to find the length of each side. Therefore, the length of each side is 78 cm divided by 3, which equals 26 cm.
