>>13976800Yes, it's clearly about 10 percent of the 100-square-unit square, which is why I accept these concurring posts
>>13980329 >>13977854 as correct. I tried flipping vertically and setting up the arcs using elementary calculus on areas between (semi)-circular curves (as opposed to polar coordinate integration) but after two rephrases I got a final answer of ~24.77 both times which is plainly false.
Still, the problem has held my interest and is now annoying me. If the original problem is flipped vertically with D being the origin, then I find Q (in the first quadrant) to be (4,8), an unexpectedly simple point, 8 being the requisite rectilinear endpoint. The calculation of this one entailed the Pythagorean triples (3,4,5) and (6,8,10), unless I goofed something (else).
Another similar problem that I did on here years ago (and actually solved correctly) involved similar frightful arc-trig things.
