Given Perimeter of square =132 cm
4 * side = 132 cm
side =132/4=33 cm.
Area of Square = 33²=1089 cm
Perimeter of circle = 132 cm.
2πr=132cm
r = 132*7/22*2
r = 21cm
Area of circle =π r²=22/7*21²=1386cm²
Difference in Area = 1386-1089=297 cm²
Circle of Perimeter 132 cm has a greater area than a square of Perimeter 132 cm by 297 cm^2.
