To find the area of a room, multiply the length times the width.
20 X 20 equals 400 sq ft.

The only answer is the trivial answer: 22.5 square feet. The area does not determine thye dimensions of the room. 22.5 square feet could be a room that is circular with a radius of approx 2.68 feet or it could be a room that is 1 mile lonf and only 0.0043 feet = 0.051 inches wide. It could be narrower still!
400 square feet.
16' x 15' = 240 square feet.
200 square feet.

20 x 20 = 400 The room has 400 square feet on the floor, 400 square feet on the ceiling, and (80 x height of the room) square feet on the walls.
20" = 2.78 square feet. Now divide the area of the tiles into the area of the room. 140/2.78 = 51 tiles
To calculate the number of 20x20 inch carpet tiles needed for a 10x12 room, first determine the area of the room in square inches. The room's area is 10 feet × 12 feet = 120 square feet, which equals 17,280 square inches (since 1 square foot = 144 square inches). Each 20x20 inch tile covers 400 square inches. Therefore, you will need 17,280 ÷ 400 = 43.2 tiles, so you'll need 44 tiles to cover the entire room.
20x20 = 400 2x4= 8 400/8= 50 needed

First we need to calculate the square footage of the room. 15*20 = 300 square feet Now we need to know how many square feet each tile covers. 20" = 1.667~ square feet 1.6672 = 2.78 square feet. Now we divide the area of the tiles into the area of the room. 300/2.78 = 108 tiles. This gives the exact number of tiles you need mathematically. Realistically you need to account for cutting and breaking. It's safe to round that up to 120 tiles.
