Question

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.

Answer 1

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
