Question

Find the area of the blue shaded region. Use 3.14 for pi. Area = ____ ft2

Answer 1

So you don't have to use pi for this problem you can do L*W
So you can do 20*36

Answer 2

Shaded region = area of rectangle - area of semicircle

= l x b - πr²/2

= 20 x 36 - 3.14 x 18/2 x 18/2 x 1/2

= 720 - 127.17
 
= 592.83 ft²

Hope this helps !!
