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.

Answer 1

We suppose that the width of rectangle is x. Then the length would be (x+4). The question says that the perimeter is 34 inches.
Perimeter is the total length of all four sides of a rectangle. So:
x+(x+4)+x+(x+4)=34
4x+16=34
4x=34-16
x=18/4
x=4.5 inches

Answer 2

Oops. I made a mistake in the calculations:
This would be;

4x+8=34
4x=34-8
x=26/4
x=6.5 inches

Answer 3

So since the width is 6.5 inches. The length would be (6.5+4)= 10.5 inches.
Sorry for that mistake.
