Willis bought a gallon of paint. he painted a wall that is 9 feet high and 10 feet wide. then he used he rest of the paint to paint 46 square feet. in the hall .how many square feet did the gallon of paint cover

First you need to find the surface area of the wall that was painted, and then add the additional area in the hallway that was painted. 

The wall that was painted was 9 feet by 10 feet, or 90 square feet. 90 square feet plus the additional 46 square feet in the hallway is 136 square feet, which is the total area that the paint covered. 

Therefore the solution is 136 square feet. 

I’m confused what’s happening
