Answer:
No her calculations do not make sense because the area of the smaller walls together is 234 and not 244 the total square feet of the windows and doors are also wrong. She should also subtract the doors and windows from the total so she doesn't over spend on paint. Her answer is correct just the way of finding it is wrong.
Step-by-step explanation:
Walls total sqft: (2(13ft)(9ft))+(2(16ft)(9ft))=234ft²+288ft²=522ft²
Doors+Windows total sqft: ((2(20ft)+(2(15ft))=60ft²+30ft²=90ft²
Total amount of paint needed: 522ft²-90ft²=432ft²
Amount of gallons needed remains the same
Hopefully this makes sense.
