Question

The perimeter of a rectangular playground must be no greater than 120 m. One dimension of the playground must be 22 m. Find the possible lengths of the other dimensions.

Answer 1

The perimeter(P) of the rectangle is calculated by the equation,
                                 P = 2W + 2L
where L and W are length and width, respectively. Using the conditions given above and letting the given dimension be the width,
                               2(22 m) + 2L ≤ 120
Solving for W gives an answer of L ≤ 38
