Question

Find the area of the shaded region
please ​

Answer 1

Step-by-step explanation:

First Lets find the area of the whole rectangle.

Area of Rectangle = length×breadth = 30 × 14 = 420 m²

Now we will find the area of the circle.

(There are two semicircles so together they form a circle)

Area of circle = πr²

radius = 14/2 = 7 m

area = 22/7 × 7²

22/7 × 49 = 22 × 7 = 154 m²

So the area of the shaded region = Area of the rectangle - Area of the circle

= 420 - 154 = 266 m²
