Answer» Correct Answer - Option 3 : 154 cm2

Given:

Perimeter of the square = 44 cm

Perimeter of square = Circumference of the circle

Formula used:

Circumference of the circle = 2πr

Area of the circle = πr2 

Calculation:

As, Perimeter of square = Circumference of the circle

⇒ 44 = 2πr 

⇒ r = 7 cm

Area of the circle = πr2 

⇒ Area of the circle = (22/7) × 72 

∴ Area of the circle is 154 cm2
