You measure or calculate the area. How you do that will depend on the shapes involved.
To calculate square footage, you multiply the length by the width of the room. So, if the room measures 10 ft. by 18 ft., your total area is 180 sq. ft.
There is a formula that calculates square footage for an area. This formula is: Area = Length x Width. By multiplying these two factors you convert feet into square feet.
Multiply by 144.
To calculate square footage of a pipe you need to use the area formula of a circle, a=1/2bh. then find the circumference of the entire pipe.

To calculate the size of air purifier you need for your house, consider the square footage of the area to be purified. Measure the length and width of the room and multiply these dimensions to get the square footage. Choose an air purifier with a recommended square footage coverage slightly higher than the size of the room for optimal air cleaning efficiency.
Base times height. This gives you the area of a rectangle or any square.
To calculate square footage, you multiply the length by the width of the room. So, if the room measures 10 ft. by 18 ft., your total area is 180 sq. ft.
The formula for calculating square footage is a=S2 (a = area and s = side) Example, to calculate the square footage of a room that is 15 feet wide and 12 long, you would multiply 15 x 12, which will give you the square footage.
Area of a semi circle: (pi*radius2)/2 square feet
Area of a circle is pi*radius^2. So if the radius is measured in feet, the area (or the square footage) of a half circle is: (pi*r^2)/2
1/2*(sum of parallel bases)*height = area
If the square footage refers to floor area, yes.
