The width of a rectangle is 4 inches longer than the length. The perimeter of the rectangle is 68 inches.

Write an equation for this situation and find the length of the rectangle.

Answer :

Answer:

Length = 15 inches.

Step-by-step explanation:

Formula for the perimeter of a rectangle:

The formula for the perimeter of a rectangle is given by:

P = 2L + 2W, where

  • P is the perimeter,
  • L is the length,
  • and W is the width.

Finding an equation relating length and width:

Since we're told that the width is 4 inches longer than the length, we can represent this with the following equation:

W = L + 4

Finding the length:

Since the perimeter is 68 inches, we can find the length by substituting 68 for P and L + 4 for W in the rectangle perimeter formula:

68 = 2L + 2(L + 4)

68 = 2L + 2L + 8

(68 = 4L + 8) - 8

(60 = 4L) / 4

15 = L

Thus, the length is 15 inches.
