Answer:
24 sq. u.
Step-by-step explanation:
1)For this triangle area, let's use the classic Euclidean formula:
[tex]\Delta \: area=\frac{b*h}{2}[/tex]
2) Let's measure the lenght of the base, taking the y coordinate of J vertex and L Vertex
[tex]|10-(-2)|=|12|=12[/tex]
3) Similarly to the height, taking the K and its distance to the base
|0-(-4)|=|4|=4
4) Plugging them in:
[tex]\Delta \: area=\frac{12*4}{2}=24[/tex]
