The diagonal of a square room can be calculated using the Pythagorean theorem. For a 20x20 room, the formula is (d = \sqrt{20^2 + 20^2}). This simplifies to (d = \sqrt{400 + 400} = \sqrt{800} = 20\sqrt{2}), which is approximately 28.28 feet. Thus, the diagonal of a 20x20 room is about 28.28 feet.
To find the area of a 20x20 room in square yards, first calculate the area in square feet: 20 feet × 20 feet = 400 square feet. Since there are 9 square feet in a square yard, divide by 9: 400 ÷ 9 ≈ 44.44 square yards. Therefore, a 20x20 room is approximately 44.44 square yards.
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.

The principal diagonal of the room also requires its height.
The diagonal is 25 feet.
To find the area of a room, multiply the length times the width. 20 X 20 equals 400 sq ft.
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.

Therefore, you will need 17,280 ÷ 400 = 43.2 tiles, so you'll need 44 tiles to cover the entire room.
Assuming the room is rectangular (as many rooms are - at least when described in floor plans), you can use the Pythagorean theorem to find the diagonal of the room - since it would be the hypotenuse of a triangle with base 15.25 feet and height 13.5 feet (decimals are easier to work with). So your diagonal is sqrt(15.252 + 13.52) = approximately 20.37 ft (20'4").
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!
Well it depends on how big you want it and how large the room is. :)
