Area = # sides * side length * apothem / 2
side length = (2 * area) / # sides * apothem
side length = 2 * 37.2 / 5 * 3.2
side length = 74.4 / 16
side length = 4.65 meters

Can i have help with this

lilavasa [31]

Answer:

Option D

Step-by-step explanation:

Square:

Side = 25 ft

Area of square = side * side

= 25*25

= 625 square ft

Area of semicircle:

diameter = 25 ft

r = 25/2 = 12.5 ft

$\boxed{\text{Area of semicircle =$ \dfrac{\pi r^{2}}{2} $}}$

$=\dfrac{3.14 * 12.5*12.5}{2}\\\\\\= 245.3 \ square \ ft$

Area of the shaded region = area of square - area of semicircle

= 625 - 245.3

= 379.7 square ft
