Question

Calculate for the area of the shaded portion. Take π=22/7.

Answer 1

Answer: 1596 cm^2

Explanation:

Area of Shaded Region = Area of Rectangle - Area of Circle

Length of Rectangle (l) = 50 cm
Breadth of Rectangle (b) = 35 cm
Area of Rectangle :-
= l * b
= 50 * 35
= 1750

Area of Rectangle = 1750 cm^2

Radius of Circle (r) = 7 cm
Area of Circle :-
= πr^2
= π * r * r
= 22/7 * 7 * 7
= 22 * 7
= 154

Area of Circle = 154 cm^2

Area of Shaded Region :-
= 1750 - 154
= 1596

Area of Shaded Region = 1596 cm^2
