    Math word problems help
    Laurence is painting the walls and ceiling of a rectangular bedroom that is 3 m by 4.5 m. The walls are 2.5 m high.
    There is a window measuring 1 m by 0.8 m on one wall and a door that is 1 m by 2.3 m in another wall.
    If a can of paint covers 20 m2 and costs $38.95, what will it cost Laurence for paint for this bedroom?

    First, draw a picture. Note the dimensions of each wall and the window and the door. Then calculate how many square meters for each wall. Then total those four numbers.

    20 sq m = $38.95
    1 sq m = $1.9425
    Cost = Total sq m x $1.9425
