The perimeter of a rectangular rug if 40 feet. its length is 12 feet. what is its width?

The width of the rectangular rug is 8 feet and this can be determined by using the formula of the perimeter of a rectangle.

Given :

The formula of the perimeter of a rectangle is:

where L is the length of the rectangle and B is the width of the rectangle.

Now, put the values of perimeter P and length L in the above equation.

Further, simplify the above expression.

W = 8 feet

The width of the rectangular rug is 8 feet.

Width is 8 ft

Step-by-step explanation:

The perimeter of the rectangle is given by the formula

P=2(l+b) (A)

Where we are given with the values as

P=40 ft

l=12 ft

Putting these values in (A)

40=2(12+b)

Dividing both sides by 2 we get

20=12+b

Subtracting 12 from both sides we get

8=b

Hence the width of the rug us 8 ft
