Question

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.

Answer 1

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
