let A = area of rectangle

let w = width of rectangle

area of rectangle = length * width, therefore:

A = 9w

then plug-in values for the width in the formula:

(a) if w=1, A = 9*1 = 9 sq. in

(b) if w=8, A = 9*8 = 72 sq. in

(c) if w=9, A = 9*9 = 81 sq. in

(d) if w=11, A = 9*11 = 99 sq. in

so there,, =)
