Question

in the adjoining figure the breadth of the rectangle is 14 cm find the area of the shaded region
​

Answer 1

Step-by-step explanation:

LENGTH OF RECTANGLE L = 14 * 2 = 28 cm

Area of rectangle A = L * B

A = 14 * 28 =392 square cm

AREA OF TWO CIRCLE = B

B =

$2 \times \pi \times {7}^{2} \\ \\ = 98\pi \\ = 308 {cm}^{2} \\ \\ required \: shaded \: area \: = \: \: \: 392 \: \: - \: \: 308 \\ = 84 \: \: \: {cm}^{2}$

Answer 2

Answer:

The length of rectangle is 28cm

So the diameter of circle is 14cm

The breadth of rectangle is 14cm
