Question

which has a greater area : a square of perimeter 132 cm or a circle of circumference 132 cm, and by how much? ​

Answer 1

Answer:

perimeter of square=132cm

side=132/4

=33

area=33×33

=1089cm^2

circumference=132cm

so,

2πr=132

22/7×2×r=132

r =132×7/44

r = 21 cm

so,

area = πr^2

=22/7×21×21

=1386cm^2

so,

area of circle is more than square by (1386-1089)cm^2

hence,

difference=297cm^2

so at last,

area of circle is more than area of a square by 297^2
