Answer 1

Composite area is 400+157=557

or 400 + 50pi

Explanation:

First find the area of the square

A=s*s A= 20*20

Area of the square portion is 400

then find the area of the semicircle- we know the diameter of the circle is 20, so the radius is 10.

so

Composite area is 400+157=557

or 400 + 50pi
