Answer:
48.3 units²
Step-by-step explanation:
To find the are of the shaded region we must subtract the area of the unshaded circle from the area of the square so we are left with the area of the shaded region.
Area of square:
Formula for the area of a square is l²
Area = 15² = 225 units²
Area of circle:
Formula for the area of a circle is πr²
Radius = 15/2 = 7.5
Area = π(7.5²) = π(56.25) ≈ 176.7 units²
Area of shaded region:
Shaded region ≈ 225 - 176.7 = 48.3 units²
