Area Of Wall Of A Room Formula

Its area bh observe the opposite walls being of the same size and shape have the same area too.

Area of wall of a room formula.

So if your room measures 11 feet wide x 15 feet long your total area will be 165 square feet. Multiply the perimeter of the room by the ceiling height to get the wall area. For the rectangle cdhg the lengths of two adjacent sides are l and h. You will need this measurement when estimating the amount of tile mortar grout and sealer that you will use for your project.

Walls to calculate the area of a wall use the standard formula of length x width area. Next use the same formula to record the individual area of windows and doors. Simplify your math by rounding inches to feet unless absolutely necessary. Sketch the surface area to be measured and record the measurements and results as you go.

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. 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 formula to find the area of the walls of a rectangular room is a 2h l b h is wall height l is room length and b is room breadth. Its area lh for the rectangle daeh the lengths of two adjacent sides are b and h.

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