Help please! 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).

Area of triangle: 18

Area of semicircle: (9pi)/2

perimeter of triangle: 20.49

perimeter of semicircle: 3pi+6

perimeter of whole thing: 23.91/ 6+8.49+3pi

Step-by-step explanation:

triangle area: 1/2bh, 1/2*6*6=18

Area of circle: pir^2, 3^2*pi, 9pi, semicircle means half, 9pi/2

answer: it is 8

step-by-step explanation:

you know why its 8
