Answer:

The coefficient of y² will be 1, which we can see when we expand the expression:

= (x +y)(x + y)

= x² + xy + xy + y²

= x² + 2xy + y²

Data

Zach = 92 ft²

x = 13248 in²

2.- Subtract the lower value to the higher value

Area = 13500 in² - 13248 in²

Area = 252 in²

3.- Conclusion

Blaise painted 252 in² more than Zach.
