Answer:

The answer to your question is Yes, she has enough paint.

Explanation:

Data

base = 12 ft

height = 8 ft

window = 3 ft x 3 ft

Process

1.- Calculate the area of the wall

Area = base x height

Area = 12 x 8

Area = 96 ft²

2.- Calculate the are of the wall

Area = side x side

Area = 3 x 3

Area = 9 ft²

3.- Calculate the area that need to be painted

Area painted = Area of the wall - Area of the window

-Substitution

Area painted = 96 - 9

= 87 ft²

4.- Conclusion

She has enough paint to paint the wall (90 ft² > 87 ft²).
