dcOne 2 Posted June 21, 2007 I'm pouring concrete, and I need an accurate measurement of the area of this (square ffeet): 4' x 14'1 x 25'8 x 10'8 x 12'11 I know that you can, (and this is what I am actually doing), is divide the shape into squares and triangles, get the measurements of those. Then if you you need to, take the area of a "easy to work with"square or rectangle, then subtract the remaining triangle that you don't need....etc, etc, etc. That's the way I am doing it, but you'd think there'd be a formula or calculator that you could punch those 5 numbers (listed above) into, and wham....have your answer.

Spider fantasy 0 Posted June 21, 2007 a five sided area? add up all the measurments and divide by 5 then multiply by 2 to get the area. I have no idea, the triangle thing might work best Share this post Link to post Share on other sites

galmgren 0 Posted June 21, 2007 I did a couple of different shaped in CAD and got areas between 95 and 130. I don't think there is a "right" answer without knowing the actual shape. Share this post Link to post Share on other sites
parrot 789 Posted June 21, 2007 I did a couple of different shaped in CAD and got areas between 95 and 130. I don't think there is a "right" answer without knowing the actual shape. 95? Really? I don't see how that could be. 4 of the 5 measurements are greater than 10 feet and one measurement is over 25 feet. A simple 4x25 rectangle would be more than 95 square feet.

dcOne 2 Posted June 21, 2007 Exactly Along with those lengths we would need angles That's what my googling told me also. I figured it the long way, and it came out to ~225 square feet. That's what I told the cement guy (who told me "You figure it out. That shape looks tough to figure out" They are out pouring it now. *gulp* You'd think you wouldn't need angles. Kinda like a piece of string in a circle. So long as you don't stretch the string, you can modify the shape however...like various sizes of ovals....and the area stays the same. You'd think it would apply to an "irregular pentagon" also, but it doesn't. Share this post Link to post Share on other sites
