In order to measure the distance AB across the meteorite crater, a surveyor at S locates points A, B, C, and D. What is AB to the nearest meter? nearest kilometer?
Draw triangle BSA (B is the bottom left corner, S is the top, and A is the bottom right corner)
line segmet DC is parallel to AB
SD=644m SC=586m CA=733m DB=800m DC=533m

I'll simplify things. I assume DC is between S and AB. Furthermore, if we assume that D and C are on lines SB and SA respectively, then we have two similar triangles, SDC and SBA.
(Actually, not quite, since SD/SB = 0.44598 and SC/SA = 0.44427), but for approximating to the nearest km, that's close enough.)
So, C/AB is approximately 0.44, and AB = 533/.44 = 1211m, or 1km.
