Question

two fields have the same perimeter. one is square of side 72m and another is a rectangle of length 80m. which field has the greater area by how much
answer must be square plot by 64m sq

Answer 1

Answer:perimeter is same so

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
