A hexagon grid with a repeating flower motif filled in to help figure out the number of repeats across and down

A single crochet hexagon being measured in the long (corner to corner) direction, but a triangle is blocked off with a piece of paper so it isn’t counted twice when laid out in a honeycomb pattern. Getting the desired dimension there will require trig to find the size of the triangle when it’s the correct size in the other direction (this hexagon is too big 😩)
