Find the are of the shaded region

Answer 1

`379.69 \: {ft}^(2)`

Explanation:

Area of the shaded region = Area of the square with side 25 ft - Area of the semicircle with radius (25/2) = 12.5 ft.

`= {(25)}^(2) - (1)/(2) * \pi * {(12.5)}^(2) \\ \\ = 625 - (1)/(2) * 3.14 * 156.25 \\ \\ = 625 - 245.3125 \\ \\ = 379.6875 \: {ft}^(2) \\ \\ = 379.69 \: {ft}^(2)`
