The width of a rectangle is 10 inches less than its length. If the perimeter of the rectangle is 36 inches. Write and solve an equation to find its width in inches.

Step-by-step explanation:

Let us suppose that length of Triangle is equal to x.

that is

Length = x

Than

width = x - 10

perimeter of Rectangle is

2 (length) + 2 (width) = 36

2x + 2 (x-10) = 36

2x + 2x - 20 = 36

4x - 20 = 36

4x = 36 + 20

4x = 56

x = 56/4

x = 14

so Length of Rectangle is 14 inches

and

width = x - 10

width = 14 - 10

width = 4
