B. 36 Square Feet.

Step-by-step explanation:

A.

Apartment 1 (first floor):

$A_1=9x*(7x+2x+2x)-3x*2x\\=9x*11x-6x^2\\=99x^2-6x^2\\=93x^2$

Apartment 2 (second floor):

$A_2=9x*(6x+3x+2x)-3x*5x\\=9x*11x-15x^2\\=99x^2-15x^2\\=84x^2$

B.

$A_1-A_2=93x^2-84x^2=9x^2\\\\x=2\\\\Thus \\A_1-A_2=9x^2=9*4=36 square feet.$
