Answer 2

☆Given

ABCD is a square inscribed in a circle

whose perimeter is 88cm

To find

To find area of shaded region

Solution

perimeter of square =4a

=>88=4a

$\because$a=22cm

Here,we see something that AC is diameter of the circle

so we have to find Ac

In right angled$\triangle$ABC

AB²+BC²=AC²

=>AC²=484+484

=>AC²=968

=>AC=√968

$\because$=22√2cm

Now r will be 11√2cm

Area of circle = πr²

=$\frac{22}{7}$×11√2×11√2

=3.14×968

~760cm²

Area of square=(side)²

=22×22

=484cm²

Area of shaded region = Area of circle-area of square

Area of shaded=(760-484)

=276cm²
