Answer :

The length of the rectangle, l = 170 m

Given,

Perimeter of the rectangle, p = 660 m

Width of the rectangle, w = 160 m

Here the formula for perimeter of the rectangle is,

Perimeter of the rectangle, p = 2l + 2w

Therefore,

Perimeter of the rectangle, p = 2l + 2w

                 660 = 2l + 2 x 160

                 660 = 2l + 320

                 2l = 660 – 320

                 2l = 340

                  l = 340 / 2

                  l = 170

That is, the length of the rectangle, l = 170 m
