Question

For the figures below, assume they are made of semicircles, quarter circles, and squares. For each shape, find the area and perimeter. Give your answer as a completely simplified exact value in terms of π (no approximations).

FIND THE PERIMETER AND AREA!!!

Answer 1

Area:

`36\pi - 72 \: cm {}^(2)`

Explanation:

`( (1)/(4) * \pi * 12 {}^(2) ) - ( (1)/(2) * 12 * 12) = 36\pi - 72`

Area of the blue area:

`36\pi - 72 \: cm {}^(2)`

Perimeter of blue area:unsure as no numbers are given for the slanted side if the triangle.
