Answer

2(l+w)

Explanation

Rectangle is a fore sided figure of which two opposite sides are equal.

Let its longer side be l and its shorter side be w.

Perimeter is the distance all round.

perimeter = l + w + l + w

                  = l+l+w+w

                   = 2l + 2w

                   = 2(l + w)
