Question 314926: the width of a rectangular picture is one-half the length. the perimeter of the rectangle is 72 inches. find the length of the picture. Answer by solver91311(24713) (Show Source):
Do this one in your head. The perimeter of a rectangle is two times the length plus two times the width, but since the width is half the length, two times the width is one times the length. So two times the length plus one times the length is three times the length is 72 inches. 72 divided by 3 is 24, and half of 24 is 12.
