The answer depends on the polygon itself and what information you have about it. There are different formulae for different situations.
Multiply by 144.
In order to calculate the square footage you need to find the length and the width of the room in feet. You multiply the length and the width to give you the square footage of the room
Multiply the length by the width to get square footage.
First of all, you need to know the radius of the tank. Second, what does outside square footage mean?
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.
Multiply by 144.
In order to calculate the square footage you need to find the length and the width of the room in feet. You multiply the length and the width to give you the square footage of the room
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.
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.
This is the simplest of equations to calculate. To calculate the square footage you will need to multiply the height X length = Square footage So 14 Ft X 32 Ft = 448 Square Feet
Multiply the length by the width to get square footage.
First of all, you need to know the radius of the tank. Second, what does outside square footage mean?
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.
length x width = area (sq. foot)
To calculate the square footage, multiply the length by the breadth. So, 10 feet x 8 feet = 80 square feet
To calculate square footage, simply multiply the length by the width, so 10 ft by 5 ft would be 50 square feet.
In general, you divide up the polygon into triangles, calculate the areas of the triangles and then sum these.
