Is there a formula for calculating area in square footage by measuring only the distance around the area in linear feet?

Area = length x width
if it's a circle
Area = 3.1415 * r^2
(pi times the radius squared)
If it's some odd trapezoid shape try these formulas:

No, you have to break up the area into geometric shapes, calculate their areas and add together. I wish there was it would make my life easier estimating bulk materials for installs.

If you have the irregular shape on a scaled plan, you can use a planimeter to get the square footage. A good digital one will run $900 or more though.
For actual, on-the-ground measurements, no, it won't work....
