Answer:
307cm²
Step-by-step explanation:
This is a composite firgue so we need to split the two shapes, then find the area of both.
find the area of the rectangle
A=b*h
A=18*10
A=180
then find the area of the semicircle
A=1/2Pi*r²
A=1/2Pi*81
A=127.75 (We need to find the radius of the semicircle then square it)
then add the two areas 180+127.75=307.75
find the closet unit its
307cm²

5=100 (5*20)
10/30= Red
75/25=Blue
10+75=85/140
Im pretty sure that the answer is
