Any help appreciated!First name variables:Width of rectangle = WLength of rectangle = L = 2W + 3 (from "...length of a rectangle is 3 more than twice its width") ................ (1)Perimeter of a rectangle = 2L + 2W = 2(2W + 3) + 2Wperimeter is 22 2(2W + 3) + 2W = 22Solve for 'W' from above - then solve for 'L' from (1)
