Jamal manages a game booth at the state fair. There is a railing along the perimeter of the rectangle. Write an expression for the amount of railing

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)
