lol well here's how i arrived at 60.
1/6 of 2160 = 360 and for some reason i divided by 6 and had 60. i'm trying to figure out why i divided by 6 but nothing is coming, maybe my brain was thinking ahead of me... ffm you might want to explain this mathematically...

how about you guys assume they are right triangles
\[A=\frac{1}{2}bh=2160 => \frac{1}{2}(6b_1)(6h_1)=2160 => \frac{1}{2}b_1h_1=60\]

area of the triangle is \( \frac12 \times \)base \(\times \) altitude
