Question

Can someone help me?

Answer 1

Answer:

see explanation

Step-by-step explanation:

Given the width is $\frac{1}{3}$ of the length, then

y - 4 = $\frac{1}{3}$(2y + 6)

Multiply through 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

Thus

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

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