The perimeter of a rectangle is 32 cm. If the length of the rectangle is 8cm more than the width, find the length and the width.

Respuesta :

x + x + x + x + 8 + 8 = 32                        Length: (x + 8) = (4 + 8) = 12cm
                    4x + 16 = 32                        Width: (x) = 4cm
                           -16   -16
                            4x = 16
                 divide by 4 on both sides
                             x =  4
