VARVARA [1.3K]

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

\frac{4*8}{2}

\frac{32}{2} = 16
