Question

Two fields have the same perimeter. One is a square of side 72m and another is around rectangle
of length 80 m. Which field has the greater area and by how much?​

Answer 1

perimeter

4(72)=2(80+b)

288=160+2b

128=2b

64=b

area of rectangle =80*64

5120

area of square=72*72=5184

area of square is more than rectangle

by 5184-5120=64
