Perimeter = 2(L + W)

Length = 85 m

Width = 55 m

Perimeter = 2(85 + 55)

= 2(140)

= 280 m

Area of rectangle = l × w

= 85 × 55

= 4675 m²

Now, let length = 80 and with = 60

Perimeter = 2(80 + 60)

= 2(140)

= 280 m

Area of rectangle = 80 × 60

= 4800 m²

Here, perimeter of the rectangle is same but Area is larger.
