Answer 1

side of square = 60cm

perimeter of square = 4 × side

= 4 × 60 = 240 cm

Area of square = side² = 60² = 3600 cm²

A rectangle with the same perimeter has a side 70 cm.

Perimeter of rectangle =

2(l+b) = 2(70 + b) = 240

70 + b = 120

b = 120 - 70

b = 50 cm

Area of rectangle = l×b = 70 × 50 = 3500cm²

Perimeter of square is equal to the perimeter of rectangle.

Area of square is more than Area of rectangle.

Hope it helps
