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

Answer:

Area:

$36\pi - 72 \: cm {}^{2}$

Step-by-step explanation:

$( \frac{1}{4} \times \pi \times 12 {}^{2} ) - ( \frac{1}{2} \times 12 \times 12) = 36\pi - 72$

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.
