The length of a rectangle is 3 feet more than the width. The perimeter is 38 feet. What are the measurements of the length and width of the rectangle? (Hint: draw a rectangle and label the sides.)

Question

please hurry dont know this

Answer 1

L = 3 + W

38/2 = W + 3 + W = 2W + 3

19 = 2W + 3

2W = 19-3 = 16

W = 16/2 = 8 feet wide

L = 8 + 3 = 11 feet long

Perimeter = 2(W+L) = 2(8+11) = 38 feet
