Question

Find the distance around each figure. Use 3.14 as an approximation for π

30. The figure is made up of a rectangle and two identical semicircles.

Answer 1

Answer: 1507.84ft^2

Step-by-step explanation:

Semicircle r = 16ft

Rectangle width = 22ft (because the radius of the semicircle is 16 and there are two of them, 2 x 16 = 32, 54 - 32 = 22)

Rectangle height = 32ft

Area of rectangle:

22 x 32 = 704ft^2

Area of circles:

16^2 x 3.14 = 803.84ft^2

No need to half the area for a semicircle because there are 2 of them

Therefore:

803.84 + 704 = 1507.84ft^2
