Write an equation to solve the following. show all your work, including the steps for solving the equation and checking your answer. clearly state your answer.
the perimeter of a rectangular photo is 72 cm. the length is twice the width.
what are the length and width of the photo?

Length     2x

Width         x

                       Perimeter = 2x + x +2x + x = 72

                                                               6x =72

                                                                 x = 72/6

                                                                 x = 12 cm

Solution:

Length = 2x = 2(12) = 24cm

Width   = x >12cm

                        Perimeter = 24cm + 12cm + 24cm + 12cm = 72cm
