Answer:
16 square units
Step-by-step explanation:
The formula for the area of a right triangle is ab/2 (a and b both being legs).
First, we find the legs' length which is MK and JK.
Since both points J and K are on the same y level, we look at the X coordinates and see how far apart they are.
Since both points M and K are on the same x level, we look at the Y coordinate.
M is 4 points away from K, so the leg MK is 4 units long.
J is 8 points away from K, so the leg JK is 8 units long.
Plug this into the formula and we get
