Set up an equation and solve. the width of a rectangle is 3 more than twice its length. the perimeter is 60 feet. find the width and length of the rectangle.

Length (L) : 2w + 3

width (w) : w

Perimeter (P) = 2L + 2w

60 = 2 (2w + 3) + 2 (w)

60 = 4w + 6 + 2w

60 = 6w + 6

54 = 6w

9 = w

Length (L) : 2w + 3 = 2 (9) + 3 = 18 + 3 = 21

Answer: width = 9 feet, length = 21 feet
