The perimeter of a rectangle is 42 inches. if the width of the rectangle is 6 inches, what is the length

Length = 15 inches

Step-by-step explanation:

Here we are given the width and the perimeter of the rectangle and we are required to find out our length. We will use the formula of perimeter in order to find the length.

The formula for perimeter

P=2(l+b)

where

l is length

b is width = 6

P is perimeter = 42

substituting them in formula we get

42=2(l+6)

dividing both sides by 2 we get

21 = l + 6

subtracting 6 from both sides we get

15 = l

Hence length is 15 inches

it is a reproduction.
