Question

The figure is made up of four identical squares of side length 12 inches. A quadrant is drawn inside each square. Find the total area of the shaded parts of the figure. Use 3.14 as an approximation for π.

Answer 1

Answer: 164.16 in²

Explanation:

Area of the shaded region = [4 quarter circles - 4*triangular regions]

= 4*(1/4)*π (12)²- 4*(12*12/2)

= 3.14(144) - 2(144)

= 164.16 in²
