Answer:

A

Step-by-step explanation:

Length : [tex]\frac{7x}{2} + 7y[/tex]

Perimeter: [tex]15x + 17y[/tex]

Perimeter = 2(Length + Width)

15x + 17y = 2( [tex]\frac{7x}{2} + 7y[/tex] + Width)

15x + 17y = 7x + 14y + 2(Width)

15x + 17y -7x -14y = 2(Width)

8x + 3y = 2(Width)

Width = [tex]\frac{8x + 3y}{2}[/tex]

Width = 4x + 3y/2
