Amap of a city shaped like a rectangle is given below on a grid. in 2012, there were 570 people per square kilometer) living in the city. what was the poplulatiok in 2012?

understand that i don't know the answers

will someone answer his question

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.

the answer on e2020 was d.
