Area Of Wall Of A Room Formula

If the perimeter is 40 feet and the height is 10 feet multiply 40 times 10 feet to get a wall area of 400 square feet.

Area of wall of a room formula.

Its area lh for the rectangle daeh the lengths of two adjacent sides are b and h. Once you have all of these measurements down subtract the area of the windows and doors from the total area of the wall. So if your room measures 11 feet wide x 15 feet long your total area will be 165 square feet. You will need this measurement when estimating the amount of tile mortar grout and sealer that you will use for your project.

For the rectangle cdhg the lengths of two adjacent sides are l and h. Its area bh observe the opposite walls being of the same size and shape have the same area too. Sketch the surface area to be measured and record the measurements and results as you go. Simplify your math by rounding inches to feet unless absolutely necessary.

Length x width area. Because most walls are square or rectangular you can determine their surface area by multiplying the width and height measurements and then subtracting any door or window space. The area of doors and windows are ignored. Next use the same formula to record the individual area of windows and doors.

Hence the total area of the four walls lh bh lh bh 2lh 2bh 2h l b.
