Answer:
You could use the formula
y^2 - y^1/ x^2 - x^1
2 - 1.6 / 5 - 4
=1.6 / 1
m= 1.6 or if you wanna put in a fraction it can be 8/5
small triangle area = 1/2(8)(14) = 56 m²
bigger triangle area = 1/2(16)(14) = 112 m²
biggest triangle area = 1/2(24)(14) = 168 m²
there's 2 bigger triangles so you pick the bigger one you want
15/4
