15 x 15 = 225 square feet
Multiply the length of one wall by the height to give you the square footage of that one wall. Then repeat for all other walls in the room and add up the total.
The length times the height of the wall will give you the square footage of that wall. Do that for both the long and short walls, and multiply the result by two. If the room is square, just measure one wall, find the square footage, and multiply by four. Don't forget to measure the length and height of any doors and windows, and subtract the total from the area of the walls.
Find the measurements from one corner along the wall to the next corner and then repeat with the wall next to it. Once you've found the measurements, multiply them together to find the square footage.
Square footage is length times height. In this case measure the entire length around the room and multiply it by the height of the wall. (15 + 18 + 15 + 18) x 15 = You do the math.
The shed covers 196 square feet of ground, and the area of its ceiling is also 196 square feet. The area of each wall is (14 x height of the shed).
Multiply the length of one wall by the height to give you the square footage of that one wall. Then repeat for all other walls in the room and add up the total.
Square footage estimates on drywall are based on the square footage of wall and ceiling that need to be covered.
The length times the height of the wall will give you the square footage of that wall. Do that for both the long and short walls, and multiply the result by two. If the room is square, just measure one wall, find the square footage, and multiply by four. Don't forget to measure the length and height of any doors and windows, and subtract the total from the area of the walls.

Percentages are used when comparing two things. I'll give you an example: You have a piece of carpet and a room to put it in, and you want to know what percentage of the floor the carpet will cover. The carpet is 100 square feet, and the room is 150 square feet. The formula is: (square footage of the carpet / square footage of the room) x 100 100/150 is .6667; multiply that by 100 to get 66.67 percent. If you want to carpet the room wall-to-wall, you need more carpet. OTOH, if you have a 200 square foot carpet and a 100 square foot room... (200/100) x 100 = the carpet is 200 percent of the size of the room, and you'll have to cut half of it off.
You normally measure the linear dimensions and then calculate the area (square footage).If you have a rectangular room, you measure its length and width in feet and then multiply the two numbers to get the area of the room in square feet. If the room is not rectangular (eg with a bay, an alcove or an L-shaped room) you will need to divide it up into simpler shapes, calculate the area of each shape and add the areas together.
36 square feet on the floor. 36 square feet on the ceiling. ( 6 x height of the room) on each wall. Total area inside the room is [ 24 times (3 + height of the room) ] square feet.
Square footage is length times height. In this case measure the entire length around the room and multiply it by the height of the wall. (15 + 18 + 15 + 18) x 15 = You do the math.
Find the perimeter of each wall and multiply L times W (LxW)
Measure the height of the wall from floor to ceiling. Measure the width of the wall. Multiply height x width = square footage. For square yards, divide the square footage by 9.
The shed covers 196 square feet of ground, and the area of its ceiling is also 196 square feet. The area of each wall is (14 x height of the shed).
