Find length and width

Question

The length of a rectangle is one foot less than four times its width. The perimeter of the rectangle is 48 feet. Find the length and width. Set up and solve using an algebraic equation. Please write a complete sentence answer.

Answer 1

L = 4w- 1

P = 48 = 2L +2w

24 = L+w = 4w-1 +w = 5w -1

5w = 25

w = 5 feet wide

L = 4(5)-1 = 19 feet Long

the rectangle is 19 feet by 5 feet
