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.

== == This below is to find the square footage for painting a room. Take the perimeter (the length in feet around the room) then multiply it by the height of the ceiling. The ceiling, which is like a 5th wall that you look up at, is measured by length X width. Same thing with the floor. Subtract about 28 sq feet per normal size door. Always get a little more paint to make sure you get the project done correctly. If the room is not a complete square, like if it has jogs in it then you want to find each box seperately by multiplying the length of the room by the width. Do this for every jog in the room then subtract each jogs' sq/ft from the sq/ft of the entire room and that with give you the rooms final sq/ft. == == == == Very simple - measure one side, then measure the side next to it and multiply one by the other. measure LENGTH x WIDTH = square footage It is very simple if the sides envolved are say a square or rectangle. If the area has for example an angular wall, measure and calculate the rectangle areas first. To get the square footage of the floor at the angled wall, measure the length and width as if the diagonal wall split your rectangle from oposite corners of your rectangle. In other words: length times width divided by two equals the square footage of this area. Then add it to all your other calculated rectangles.

If you're trying to find the total area of 4 walls:(Length of wall 1 x width of wall 1) + (Length of wall 2 x width of wall 2) + (Length of wall 3 x width of wall 3) + (Length of wall 4 x width of wall 4) = total areaThe area enclosed by four walls if they form a rectangle or square is length x width.The area of a rectangular wall is hw where h is the height and w is the width. In an ordinary rectangular room, there are 4 walls and opposite walls are equal, and the heights are all equal, formula is A = hw1 + hw2 + hw1 + hw2 = 2hw1 + 2hw2 = 2h ( w1 + w2) , where the floor is w1 by w2.If the floor is square, w1 = w2 and the formula simplifies to A = 4hw1.

Square

on a wall it would be 100 square feet.

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 square footage of a 25,000 gallon pool depends on the shape of the pool. To determine the square footage multiply the floor width with the floor length. Multiply the length by the height of the walls for each wall. Add all these numbers together to get the square footage.

That depends on why you need the square footage. For building permits, tax assessments, etc. it is the outside; for floor covering of course the inside...

Square footage estimates on drywall are based on the square footage of wall and ceiling that need to be covered.

You must know the total square footage of the area you need siding for. Once you know the square footage, any sales outlet can help figure the amount of siding needed. The square footage can be calculated using the length of the wall multiplied by the height of the wall.

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.

When you say "square footage", that usually means the area of the floor, and yes, you get that by multiplying (length of the room) x (width of the room). That tells you how much carpet you need for the floor. The walls and the ceiling also have their own "square footage". You have to know that to do things like paint and wallpaper. The ceiling has the same area as the floor. But for the walls, you have to do another whole different calculation. The easy formula for square footage of the walls is circumference (the distance around the room at the floor level) X the height of the wall (at the tallest point if the walls are uneven or have a peak). If the walls have a large number of windows, doors or other areas not to be painted, you may want to figure the rough square footage of these (estimate low, better to have a bit too much paint than a bit too little) and subtract that from your total. If you are estimating square footage for paint remember you may want to do two coats. If you are estimating for wallpaper, be sure to allow for the "pattern repeat".

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.

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.

15 x 15 = 225 square feet
