View Full Version : Figuring square footage.
We do 4 U

I know for a sguare area it is lenght x width. But who do you figure for odd shaped lawns, beds, etc? I am not math wiz ( or any kind of wiz if every there was a wiz that was).
Thanks in advance.

Area of a triangle is figured by measuring similarly to a rectangle or square area. Measure two ajoining sides, multiply them as if you would be doing the area as mentioned above and then divide by two, that is basically getting the area of a square or rectangle that has been cut diagonally, thus creating a triangle.
The area of a circle is 3.14 x (radius x radius).
Sorry, but I can't figure out how to get mathmatical symbols on the keyboard.
The radius is half the diameter. The diameter being the distance from one side to the other of the circular area you are attempting to measure.
First multiply the radius by itself, then mulyiply it by pi (3.14) and that will be your area.
Hope I haven't confused you...

Square (or rectangle) it off in your head while you measure it, this aint rocket sceince.

I just use length x width and subtract the obstacles if they are substantial. I can see where you would need to be more precise though. If you're ordering sod for example. Is there anything particular that you're trying to measure?

I know that you want to be as precise as possible, but there is room for error. Take areas that are not necessarily perfect squares or rectangles in shape and make them those shapes by sectioning areas off, and then adding on a fudge factor - either for or against your calculations.
The reason I say this is because when measuring many properties in a day or week or on a regular basis, you do not want to spend too much time trying to get the exact square footage - you may be wasting time. You'll see if you measure a few lawns precisely using any formular described above and then figuring it with a fudge factor, you will be fairly close every time.
Even if you added up the mistakes in square footgae, you still won't have lost much.

You've got the area of a square == length X width
The area of a retangle is the figured the same == L X W
A triangle is 1/2 the base times the height so measure 1/2 the base and multiple it time the height. example: the base of a triangle is 20 feet and the height is 8 feet. take 1/2 the base (10 ft) time the height (8 ft)= 80 sq ft
A circle is 3.14 X radius X radius == measure from the center of the circle to its edge. Multiple that number times itself and than multiple the answer by 3.14. example: suppose the center of a circle to its edge is 10 feet-- multiple 10 ft X 10 ft = 100, now multiple by 3.14. (100 X3.14)= 314 sq ft.
using the formulas, take your area you're trying to measure and divide it into a series of squares, circles, triangles, figure the sq footage of each and them together.
