The red triangle in the video has a base of 8 inches and a height of 5 inches. What did they say the area of that triangle was?
- A.
40 square inches
- B.
20 square inches
- C.
4 square inches

Coach Huddleston needs to put a fence around the football field. The field measures 100 feet by 35 feet. How many feet of fencing does he need to buy?
- A.
270 feet
- B.
135 feet

400 feet
- D.
140 feet
Correct Answer
A. 270 feetExplanation
To calculate the amount of fencing needed, we need to find the perimeter of the football field. The formula for perimeter is 2(length + width). In this case, the length is 100 feet and the width is 35 feet. Plugging these values into the formula, we get 2(100 + 35) = 2(135) = 270 feet. Therefore, Coach Huddleston needs to buy 270 feet of fencing.Rate this question:

A rectangle has a length of 10 cm and a width of 6 cm. What are the area and perimeter of the rectangle?
- A.
Area: 60 cm², Perimeter: 32 cm
- B.
Area: 60 cm², Perimeter: 26 cm

Area: 40 cm², Perimeter: 26 cm
Correct Answer
A. Area: 60 cm², Perimeter: 32 cmExplanation
The area of a rectangle is found by multiplying the length by the width. So, 10 cm times 6 cm equals 60 cm².
The perimeter of a rectangle is found by adding together the lengths of all four sides. So, 2 times (10 cm plus 6 cm) equals 32 cm.
Therefore, the correct answer is: Area: 60 cm² Perimeter: 32 cmRate this question:
