The length of a rectangle is 5cm more than twice the width. The perimeter of the rectangle is 34 cm. Find the dimensions of the rectangle. So confused on how to do this problem please help me thanks.

Question

Dr. Jane · Answer

Perimeter = L + L + W + W

or P = 2L + 2W

L = 5+ 2w

P = 2(5+2W) + 2W

I replaces the L in the original formula with the 5 + 2w because that equals L according to the problem.

34 = 10 + 4W + 2W

Just solve for W.

And then you can find L.
