Gusset (perimeter) length

[wizcam777]

I don't know enough about math to even know what thread I should post my question.

I am doing Leather work and I was wondering if their is a formula for figuring out the gusset length for a bag?
Or I guess I should say the length from 1 corner around to the other corner, do not include the top line
Is this possible?

Do you know the formula for the perimeter of a rectangle?

Are the corners rounded as quarter circles?

Do you know the formula for the perimeter of a circle (or quarter circle) ?

I do not know the formula for the perimeter of a rectangle. did not know there was one.
The corners are usually rounded like the picture I attached.
Do you know the formula for the perimeter of a circle (or quarter circle) ? Sorry I do not
I could look those formulas up , but I would not know how to combine them do find what I need.

Looked up the first one -- P=2(l+w)
this one looks like it will give me the distance all the way around and the I could subtract the top line length
but I have no Idea what to do with C=2πr and how to subtract or add that to my final dimension

Formula? If the holes are equally spaced, you can just count the holes. No?

Never thought about counting the holes to get the length. Yes the holes are evenly spaced, as is the space from the end to the first hole. while the last hole and the end may not be the same as the start, I can use the tools in inkscape to get that distance.

Thanks guys

This is why we don't like to answer the question "What's the best way to …?" If we know only one way to solve problems, we limit ourselves severely. Sometimes, solutions are more complex than we imagine, at first. No always. Glad we could help.
