Answer 1

Here are the answers to an area and perimeter unit test:

1. What is the formula for the perimeter of a rectangle?
Answer: Perimeter = 2*(length + width)

2. What is the formula for the area of a triangle?
Answer: Area = 0.5 * base * height

3. If a rectangle has a length of 10 cm and a width of 5 cm, what is its perimeter?
Answer: Perimeter = 2*(10 + 5) = 2*15 = 30 cm

4. If a triangle has a base of 8 cm and a height of 6 cm, what is its area?
Answer: Area = 0.5 * 8 * 6 = 24 cm^2

5. What is the formula for the perimeter of a square?
Answer: Perimeter = 4 * side length

6. If a square has a side length of 4 cm, what is its perimeter?
Answer: Perimeter = 4 * 4 = 16 cm

7. What is the formula for the area of a circle?
Answer: Area = π * (radius)^2

8. If a circle has a radius of 3 cm, what is its area? (Use π = 3.14)
Answer: Area = 3.14 * (3)^2 = 3.14 * 9 = 28.26 cm^2

9. What is the formula for the circumference of a circle?
Answer: Circumference = 2 * π * radius

10. If a circle has a radius of 5 cm, what is its circumference? (Use π = 3.14)
Answer: Circumference = 2 * 3.14 * 5 = 31.4 cm
