Need math help on DIY tarp
Sorry to admit, but I should have paid more attention in math.
I am trying to get ready to make a heated winter hammock tarp with
a stove jack. Before I cut into some very expensive soft structure
tyvek 1460uv, I want to make a mock up version from an old blue poly tarp.
Rather than cut the profile I want and sew two identical pieces together, I
wanted to make this from a single piece to avoid a ridgeline seam.
I am having trouble with layout. Would anybody here be able to tell me what
my dimensions are where I have marked 'A' and 'B'. That would be most
appreciated. I hope I am not missing any vital info.
Please excuse the crudeness of my drawings. I realize they are incorrectly scaled
and in actuality my tarp is nearly square. It didn't start out that way. I just made
the image and then started playing around with the numbers until they matched a
full scale tarp I had set up in the garage.
If someone could help me out so I dont screw this up. That would be fantastic.
Thank you in advance.
