Respuesta :

area of the square + area of 4 semicircles.

use s² to find the area of the square. s=8
s²=18²=324

use πr²/2

=(3.14 x 324)/2
508.9

4 semi circles right, 
4 x 
508.9
=
2035.8

total area = 
2035.8 + 324 
2359.8 ft²

total area = 2035.8 + 324 
2359.8 ft²  

total area = 2035.8 + 324 
2359.8 ft²
