    Answer:2.73 gallons of paint is needed.

    Step-by-step explanation:

    There are four walls in the room. The opposite walls are equal in length and width.

    Maria has a rectangular room whose dimensions are 22 feet by 17 feet, with 7 -foot ceilings.

    The formula for determining the area of a rectangle is expressed as

    Area = length * width

    Area of each of the longer sides would be 22 * 7 = 154ft². Therefore, Area of the 2 longer sides would be

    2 * 154 = 308ft²

    Area of each of the shorter sides would be 17 * 7 = 119ft². Therefore,. Area of the 2 shorter sides would be

    2 * 119 = 238ft²

    Total area = 308 + 238 = 546ft²

    Since there would be 2 coats of paint on the wall, the wall would be painted twice. The total area becomes

    546 * 2 = 1092 ft²

    If a gallon of latex paint can cover 400 square feet, then the amount of paint needed would be

    1092/400 = 2.73 gallons

    So, we have 17 (9) = 153 and 25 (9) = 225

    2 (153 + 225) = 756

    Since we need 2 coats, 2 (756) = 1512

    1512/400 = 3.78

    Buying 3 gallons would cover 1200 square feet, so we'll need to buy a fourth to cover the rest and have some paint left over.
