Jonathan has created a new pencil that is in the shape of a triangle. He is trying to develop the best way to market this invention. His pencil seems to be a bit awkward and no sides are the same. He calls it the Scalene Pencil by Big "J". His triangle has side lengths of 3 cm., 1.6 cm., and 2.2 cm. What is the perimeter of his new invention?

• A.

8.6 cm

• B.

6.8 cm.

• C.

6.6 cm.

• D.

4.8 cm.

B. 6.8 cm.
Explanation
The perimeter of a triangle is the sum of the lengths of its sides. In this case, the triangle has side lengths of 3 cm, 1.6 cm, and 2.2 cm. Adding these lengths together, we get a sum of 6.8 cm. Therefore, the perimeter of Jonathan's new invention, the Scalene Pencil, is 6.8 cm.

Rate this question:

• 2.

A triangular field has a base of 14 m and a height of 18m. What is the area of the field.

• A.

252 square meters

• B.

64 square meters

• C.

126 square meters

• D.

504 square meters

C. 126 square meters
Explanation
The area of a triangle is calculated by multiplying the base by the height and dividing the result by 2. In this case, the base is 14 m and the height is 18 m. So, the area of the triangular field would be (14 * 18) / 2 = 126 square meters.

Rate this question:

• 3.

If the base of a rectangle is 25 m and the area is 175 m2, what is the height of the rectangle?

• A.

21,875 m

• B.

100 m

• C.

35 m

• D.

7 m

D. 7 m
Explanation
The area of a rectangle is calculated by multiplying its base by its height. In this case, we know that the base is 25 m and the area is 175 m2. To find the height, we can divide the area by the base. 175 m2 divided by 25 m equals 7 m. Therefore, the height of the rectangle is 7 m.

Rate this question:

• 4.

Classify this triangle.  Choose all names that would apply

• A.

Isosceles

• B.

Scalene

• C.

Right

• D.

Obtuse

• E.

Acute

A. Isosceles
C. Right
Explanation
The given triangle can be classified as isosceles because it has at least two sides that are equal in length. It can also be classified as right because it has one angle that measures 90 degrees.

Rate this question:

• 5.

Classify the triangle above

• A.

Acute Scalene

• B.

Right Scalene

• C.

Right Isosceles

• D.

Obtuse Sclene

• E.

Acute Isosceles

D. Obtuse Sclene
Explanation
The triangle is classified as an Obtuse Scalene triangle because it has one angle that measures more than 90 degrees (obtuse) and all three sides are of different lengths (scalene).

Rate this question:

• 6.

Find the missing angle

• A.

40

• B.

110

• C.

80

• D.

70

D. 70
Explanation
The missing angle can be found by subtracting the sum of the given angles from 180 degrees, since the sum of the angles in a triangle is always 180 degrees. In this case, 40 + 110 + 80 = 230, so the missing angle can be found by subtracting 230 from 180, resulting in 70 degrees.

Rate this question:

• 7.

Classify the triangle.

• A.

Scalene Isosceles

• B.

Acute Scalene

• C.

Acute Isosceles

• D.

Obtuse Scalene

C. Acute Isosceles
Explanation
The given answer, "Acute Isosceles," suggests that the triangle being classified is both acute and isosceles. An acute triangle is a triangle in which all three angles are less than 90 degrees. An isosceles triangle is a triangle with at least two sides of equal length. Therefore, the answer implies that the triangle in question has two equal sides and all three angles are less than 90 degrees.

Rate this question:

• 8.

A triangle has the following angle measurements:  62 and 57. Classify this triangle by its sides and angles.

• A.

Obtuse Isosceles

• B.

Right Scalene

• C.

Obtuse Scalene

• D.

Acute Scalene

D. Acute Scalene
Explanation
Based on the given angle measurements of 62 and 57, we can determine that this triangle does not have any angle measuring 90 degrees or more, making it an acute triangle. Additionally, since none of the sides have equal lengths, it is a scalene triangle. Therefore, the correct classification for this triangle is "Acute Scalene".

Rate this question:

• 9.

A triangle has the following angle measurements:  58 and 73.  What is the missing angle measurement?

• A.

131

• B.

90

• C.

27

• D.

49

D. 49
Explanation
Since a triangle has a total of 180 degrees, we can find the missing angle by subtracting the sum of the given angles (58 + 73 = 131) from 180. Therefore, the missing angle measurement is 49 degrees.

Rate this question:

• 10.

A. Obtuse
D. Isosceles
Explanation
The triangle in the question has one angle that is greater than 90 degrees, making it obtuse. Additionally, it has two sides that are equal in length, making it isosceles.

Rate this question:

• 11.

An equilateral triangle can be classified as an isosceles.

• A.

Dr. McLaughlin designed a new bulletin board in the shape of a parallelogram. The base of the board is 471.5 cm., Ā the height is 21.3 cm., and the side length is 24 cm. What is the perimeter of the McLaughlin B-Board?Ā

• A.

991 cm.

• B.

965.6 cm

• C.

10,316 cm

• D.

10,042.95 cm

A. 991 cm.
Explanation
The perimeter of a parallelogram can be found by adding up the lengths of all its sides. In this case, the base and the opposite side of the parallelogram are equal in length, so the perimeter is twice the length of the base plus twice the length of the side. Therefore, the perimeter is 2(471.5 cm) + 2(24 cm) = 943 cm + 48 cm = 991 cm.

• B.

60 square units

• C.

35 units

• D.

54 square units

• E.

None of the above

Rate this question:

• 14.

Why might you want to measure the area?

• A.

To know how much it will cost me to put carpet in my home

• B.

To know how much grass seed I need for my yard

• C.

All of the above

• D.

None of the above

C. All of the above
Explanation
Measuring the area is important because it allows you to determine the amount of carpet needed for your home, which is essential for estimating the cost. Additionally, measuring the area helps in determining the amount of grass seed required for your yard, ensuring that you buy the right quantity. Therefore, the correct answer is "All of the above" as both options are valid reasons for wanting to measure the area.

Megan wants to build a fence around her vegetable garden. Her garden is 8 ft. long and 3.25 ft wide. How much fencing will Megan need for her wonderful garden?

• A.

26 sq ft

• B.

22.50 ft

• C.

11.25 sq ft

• D.

24 ft

B. 22.50 ft
Explanation
Megan wants to build a fence around her vegetable garden, which is 8 ft long and 3.25 ft wide. To calculate the amount of fencing she needs, we add up the lengths of all four sides of the garden. The two lengths are 8 ft each, and the two widths are 3.25 ft each. Adding these together gives us a total of 22.50 ft of fencing needed.

What is the height of a rectangle with perimeter 126.6 mm and base length 40.4 mm?**Draw a picture to help**

• A.

86.2 mm

• B.

45.8 mm

• C.

22.9 mm

• D.

5114.64 mm

C. 22.9 mm
Explanation
The perimeter of a rectangle is equal to the sum of all its sides. In this case, the perimeter is given as 126.6 mm. We are also given the length of the base as 40.4 mm. To find the height, we need to subtract the length of the base from the perimeter, and then divide the result by 2 (since the other two sides are equal in length). So, (126.6 - 40.4) / 2 = 86.2 / 2 = 43.1 mm. Therefore, the height of the rectangle is 43.1 mm.

Find the area of a triangle with a height that is 5 m and half of the base is 9m.

45 meters squared
45
45m2
45 meter squared
Explanation
The area of a triangle can be calculated using the formula: Area = (1/2) * base * height. In this case, the height is given as 5m and half of the base is given as 9m. Therefore, the full base would be 2 * 9m = 18m. Substituting these values into the formula, we get: Area = (1/2) * 18m * 5m = 45m^2. So, the correct answer is 45 meters squared.

Arusha needs to buy fertilizer to spread in her garden. The garden is 20 feet by 15 feet. How much fertilizer will she need to cover her garden?

300 feet squared
300
300 ft2
300 ft squared
Explanation
Arusha needs to buy fertilizer to cover her garden, which is 20 feet by 15 feet. To find the area of the garden, we multiply the length by the width. So, 20 feet multiplied by 15 feet equals 300 square feet. Therefore, Arusha will need 300 feet squared of fertilizer to cover her garden.
