The length of a rectangle is 4 centimeters less than twice its width. The perimeter of the rectangle is 34 cm. What are the dimensions of the rectangle?
Width = w Length = w-4 Perimeter = 34 34 = ((w-4) * 2) + (w * 2) So based on my calculations w = 10.5 So the length is 10.5 - 4 = 6.5 Let's see if this is correct. 34 = ((10.5 - 4) * 2) + 10.5 * 2) 34 = (6.5 * 2) + (10.5 * 2) 34 = 13 + (10.5 * 2) 34 = 13 + 21 34 = 34
