Question

The length of a rectangle is 4 inches more than its width, and its perimeter is 34 inches. Find the length and width of the rectangle. Find the width of the rectangle. Type a numerical answer in the space provided. Do not include labels or spaces in your answer.

Answer 1

Answer:

6.5 inches = width

length = 10.5 inches

Step-by-step explanation:

let width = w,  then:-

2w + 2(w + 4) = 34

4w = 34 - 8 = 26

w = 26/4 = 6.5 inches

Answer 2

Answer:

The width of the rectangle is 6.5 in.

Step-by-step explanation:

Here L = W+4.  Then P = 2L + 2W = 34 in = 2(W+4) + 2W = 4W + 8.

Solving for W, we obtain 34 in = 4W + 8, or 26 in = 4W, or W = 6.5 in.

Then L = W+4 = 10.5 in.

Check:  P = 2W + 2L must equal 34 in.  Does 2(6.5 in) + 2(10.5 in) = 34 in?  Yes.
