Question

What is the approximate area of the shaded region

Answer 1

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

Answer 2

The correct answer is

21.5 square centimeters

Step-by-step 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 = (l)/(2) = (10)/(2) = 5cm`

This implies that,

Area of shaded region

`= {10}^(2) - \pi * {5}^(2)`

`= 100 -25 \pi`

`\approx21.5 {cm}^(2)`
