Any mathmeticians here

I dunno, my trig may be rusty but 6 down the middle of the 180 length should do it. . .

1st one starts 41' from sideline and the rest are spaced 82'

I could be wrong but I think that does it

Again, just curious as to why you'd want so many hoses and spigots? That's bigger than a football field.

They don't seem to want to answer this question because a few have asked now

Simple cheat: Download the Rainbird Sprinkler Design Software.

Let it optimize for heads with 100-ft reach. Then install quick coupling valves everywhere the software says to put a head.

As one of my engineering professors said, "Plagiarize, there are a lot of really good ideas out there that are off patent. Look into what the last guy did, so you don't waste time reinventing the wheel."

I thought about that as well, but I think it'll want to put them in the corners, along the edges, and down the middle, like a normal sprinkler system would do.

The OP specifically said they want them along the edges only, and, that they were going to definitely put them in the corners as well.

It sure would help to understand the intended usage.

You could do what I do and just use longer length of hose. I have three hoses connected together and I can reach any spot on my 2 acre rectangle from the back of my house.

My wife is 70 years old, she has trouble with one 100 fter

May I suggest along with your hoses this sort of shut off valve: https://www.amazon.com/dp/B0D66GQ5Q3

It's definitely a full-flow design - the ball in the valve has a very large hole in it.

It came with the nut on very tight; comes with a ridiculous little wrench none of us need.

Great thing to put on the end of a 100' hose because you can take your time walking from the hose bib to the end and not spill tons of water in the meantime.

I've bought a few of them now and love them. With it cracked open just a bit it's got a decent spray that I use to water a spot that I used to use as a burn pile till last year and now have wildflowers growing; wide open it fills up a tub as fast as your pump and hose can manage. I bought 50' and 100' 3/4" hoses from HF a couple years ago and so far so good.

Who'd have ever thunk that we could fill 5 pages on "how many hose bibs do I need?" I mean, the area is a simple rectangle, not exactly complex spherical geometry.

Actually that brings up a good question - the land is supposedly rectangular, but is it flat? Discuss.

My scale is a bit off...

Putting the hydrants at the border might make more sense from a land use standpoint not having them in the way but strictly based on covering the area you’re wasting half the potential radius putting them on the perimeter.

What is being watered is a pretty important part of this problem.

If it is grass, the spigot system would work.

If you are watering plants, you are going to destroy them as you drag the hose over them.

More details would help get a better answer.

For that large an area a permanent sprinkler system might be a better solution.
