<h3>Area of shaded region is 21.5 square centimeter</h3>
<em><u>Solution:</u></em>
The area of the shaded region is equal to the area of the square minus the area of the circle
<em><u>
Find the area of the square</u></em>

Where, "a" is the length of each side
From given figure in question,
a = 10 cm

<em><u>Find the area of circle
</u></em>
The area of the circle is given as:

Where, "r" is the radius of circle
Diameter = 10 cm

Thus,

<em><u>Find the area of the shaded region</u></em>
Area of shaded Region = Area of Square - Area of Circle
Area of shaded Region = 100 - 78.5 = 21.5
Thus area of shaded region is 21.5 square centimeter
