Asked by harshp2303 | 07 Mar, 2019, 07:58: PM
Expert Answer
Perimeter of square = 44 cm ; if a is side of square, side a = 44/4 = 11 cm ; area of square = 11×11 = 121 cm2
Perimeter of circle = 44 cm; if r is radius of circle, radius r = 44/(2π) = (44 7)/(2×22) = 7 cm ;
Area of circle = πr2 = (22/7)×7×7 = 154 cm2
