Problema Solution

the perimeter of a rectangle is 68cm.if the diagonal is 26cm.find the di.mensions of the rectangle

Answer provided by our tutors

Let L = length and W = width of the rectangle


We know the perimeter is 68, so L+W = 34, and:

L = 34 - W


Using the Pythagorean theorem, with the diagonal as the hypotenuse, we know:

L² + W² = 26²


Using substitution, we can solve for W:


(34 - W)² + W² = 26²


1156 - 68W + 2W² = 676


2W² - 68W + 480 = 0


W² - 34W + 240 = 0


(W - 10)(W - 24) = 0
