@jdoe0001 @jim_thompson5910 can yal help?

Answer 2

got picture?

Answer 3

No @jdoe0001

Answer 4

notice the triangle, left side give the coordinates

notice the the altitude, or height, right side

so you'd need to find the BASE and the ALTITUDE or HEIGHT of the triangle
that is, the distance between XW and YZ to get the triangle's area
recall that \(\bf \textit{triangle's area}\cfrac{1}{2}\cdot base\cdot height\)

Answer 5

Can you explain how i do that?
