Answer:
length = 13 feet and width = 5 feet
Step-by-step explanation:
let width be w then length is 2w + 3 ( 3 more than twice the width )
Equate the sum of length and width to 18, that is
w + 2w + 3 = 18, that is
3w + 3 = 18 ( subtract 3 from both sides )
3w = 15 ( divide both sides by 3 )
w = 5
That is the width is 5 feet and
length = 2w + 3 = (2 × 5) + 3 = 10 + 3 = 13 feet
