The length of a rectangle is 3 yd longer than its width. If the perimeter of the rectangle is 70 yd, find its length and width.

Question

please give me the answer to this problem!

Answer 1

Perimeter = 2L + 2W. In this case L = W + 3 so can substitute for L in the formula.

P = 2(W + 3) + 2W. Simplify by using the distribution rule and use P = 70 to solve for W. Then can find L.

Check your result to be sure total perimeter is 70.
