Length of square = 72m
Perimeter = 4a = 4*72 = 288m
Area = a^2 = 72*72 = 5184 msq
Perimeter of rectangle = perimeter of square = 288m
length of rectangle = 80
perimeter of rectangle = 2(L+B)
288 = 2(80+B)
144 - 80 = B
B = 64
Area of rectangle = L*B = 80*64 = 5120 msq
hence we can tell area of square is greater
5184 - 5120 = 64 msq
by 64msq square area is greater than that of rectangle

perimeter of square=72×4=288m
perimeter of rectangle= 2(80+b)= 288
= 80+b= 144 m
= b= 64m
area of square= 72× 72= 5184 sq m
area of rectangle= 80×64=5120 sq m
area of square is greater by 64 sq m
perimeter of rectangle= 2(80+b)= 288
= 80+b= 144 m
= b= 64m
area of square= 72× 72= 5184 sq m
area of rectangle= 80×64=5120 sq m
area of square is greater by 64 sq m
