Can someone find the area of this rectangle please?x

72 cm^2

Step-by-step explanation:

If the Length is twice the Width, then W = W and L = 2W.

The perimeter formula is P = 2W + 2L, which here is:

                                      36    = 2W + 2(2W), or

                                        36 = 2W + 4W = 6W; then W = 6 and L = 12.

The area formula is A = L * W, which here is:

A = 6*12 = 72 cm^2
