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

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
