Heya,
Here is your answer.

☆ Given :
l = 11m
b = 8m
☆ Perimeter of the rectangle = Circumference of the circle.
Perimeter = 2 (l+b)
= 2 × (11+8)
= 2×19 = 38 m
☆ So, Circumference of the circle = 38 m
2 pie r = 38
= 2×3.14×r = 38
= 6.28×r = 38
r = 38/6.28
= 6.05 m
☆ Area = 2 pie r^2
= 2×3.14×(6.05)^2
= 227.58 (approx.) is the area if the circle.
Hope it helps..
