I assume the 2100 sq ft is the ground cover. It will require each wall to be measured and added together to get the overall interia messurements
to get sq ft - is height multiplied by width of wall
Therefore - a wall 15 feet high and 20 feet long will be 15x20 = 300sq ft

Multiply by 144
If you mean a circle then its square footage formula is: pi*radius2
Treat it as a square and half the result.
Length x width of the interior edge of the foundation. Also, add the dimension of any attached enclosed garage in the figure. Non-enclosed or detached garage or car port do not apply.
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.

To figure out the square footage of this odd sized room, you simply need to multiply the numbers. The answer is 2720 square feet.
For a parking lot to have 3 measurements, it must be an unusual shape. We would need more information to figure the square footage.
Length x width of the interior edge of the foundation. Also, add the dimension of any attached enclosed garage in the figure. Non-enclosed or detached garage or car port do not apply.
Area in square feet = pi*radius2
a roofing square is 100 sf. There are formulas out there that allow you to use the pitch and outer dimensions of the roof to figure out the number of squares. If not, calculate the square footage and divide by 100 - that's the number of squares you have...
I use algebra to figure square footage, cubic footage, and angles when building, It is very important.
length x width = area (sq. foot)
