Question

The width of this rectangle is 1/3 of the length. Find the width of the rectangle

Answer 1

length = 42 in , width = 14 in

Explanation:

given the width is
`(1)/(3)` of the length , then

y - 4 =
`(1)/(3)` (2y + 6) ← multiply both sides by 3 to clear the fraction

3y - 12 = 2y + 6 ( subtract 2y from both sides )

y - 12 = 6 ( add 12 to both sides )

y = 18

then

length = 2y + 6 = 2(18) + 6 = 36 + 6 = 42 in

width = y - 4 = 18 - 4 = 14 in
