Calculate length of tarp needed to extend 12 linear feet (at 0 degrees), but sloping at 25 degrees instead
Posted on 2008-06-19
I need to cover an area with a tarp, but sloping downward to allow rain to run off.
The area to be covered is 12 feet long (ground/linear measurement).
The tarp will start 9 feet above the ground and slope downward at roughly a 25 degree angle.
How much length of tarp will I need to cover the 12 linear feet after adjusting for the slope?
|*tarp starts here, 9 feet up
|**angled down at ~25 degrees
|__________________________________12 feet of concrete, end of area to be covered
Would be great if you could include the formula too :-) .
