Question

In the adjoining figure, the length of the rectangle is 28 $cm$Find the area of the shaded region.

Answer 1

The length of rectangle is $28cm$

So the diameter of circle is $14cm$

The breadth of rectangle is $14cm$

The area of shaded part is given as

$\frac{1}{8}$ part of rectangle $-\frac{1}{4}$ part of circle

$\frac{1}{8}\times 14\times 28-\frac{1}{4}\pi 7^{2}49-\frac{49\pi }{4}=\frac{147\pi }{4}$
