Answer:
Option A
Explanation:
Area of shaded region
Square:
Side = 12 m
Area of square = Side *side
= 12 *12
= 144 square m
Circle:
diameter = side of the square
= 12 m
r = 12/2
r = 6 m
Area of circle = πr²
= 3.14 *6 * 6
= 113.04 m²
Area of the shaded part = area of square - area of circle
= 144 - 113.04
= 30.96 m²
