Question

you want to determine how many gallons of paint you need to buy to paint your bedroom. when youre painting a room, you need to determine how many square feet you intend to cover. when measuring a wall, dont include baseboards, crown molding, or other trim, as youre likely to be painting those with a different type of paint or color. to get an accurate measurement, you will want to first find the area of your walls and then subtract the area of any doors and/or windows that you have in your room. remember the area of a rectangle equals length times width.
there are 4 walls in your room that you want to paint. each wall is 15 feet by 22 feet. find the total area of all 4 walls. hint: for this question, pretend there are no doors or windows in this room. the total area of all 4 walls is ________ square feet.

Explanation:

Step1: Calculate area of 1 wall

Area = length × width = $15 \times 22$ = 330 square feet

Step2: Calculate total area of 4 walls

Total area = 4 × area of 1 wall = $4 \times 330$

Answer:

1320 square feet
