Question

Two fields have the same perimeter.
One is a square of side 72m.
Another one is a rectangle of
length 80m. Which plot has a
greater area?

Pls say the answer

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
