Question

What is the approximate area of the shaded region

Answer 1

ANSWER

The correct answer is

21.5 square centimeters

EXPLANATION

The shaded area is the area of the square minus the area of the Circle.

Area of shaded region

$= {l}^{2} - \pi \: {r}^{2}$

From the diagram,

$l = 10cm$

and

$r = \frac{l}{2} = \frac{10}{2} = 5cm$

This implies that,

Area of shaded region

$= {10}^{2} - \pi \times {5}^{2}$

$= 100 -25 \pi$

$\approx21.5 {cm}^{2}$

Answer 2

The answer would be 21.5 square centimeters. Hope this helps!
