Answer:
a) 154 cm
Side of the square=11cm
Perimeter of a square= 4×side
= 4 × 11 = 44 cm
Given perimeter of the square is equal to the circumference of the circle
So circumference of the circle is also equal to 44cm
Now, circumference of the circle= 2πr
2 × 22/7 ×r= 44cm
r= 7cm
So the area of the circle = πr^2
Area of the circle = 22/7 × 7 × 7
=154cm
