Answer:

Step-by-step explanation:
1) so you want to simplify this monomial first
(divide coefficients by 7)
(3x^6y^5)/2x^2y^9
2) next, you want to eliminate the extra "x" and :y: values
(bring x value with smaller power to the higher power x value)
so
(3x^6*x^-2y^5)/2y^9
(3x^4y^5)/2y^9
(do same thing for "y")
(2x^4)/2y^4

6 inches enlarged by 1.5 = 9 inches
9 inches enlarged by 1.5 = 13.5 inches
area = 9 × 13.5
= 121.5 square inches
