Use Heron's Formula:
s means semi-perimeter = (50 + 31 + 18) / 2 = 99 / 2 =
49.5
area = sq root [(s * (s-a) * (s-b) * (s-c)]
area = sq root [(49.5 * (s-a) * (s-b) * (s-c)]
This will NOT form a triangle. The longest side (50) is greater than the sum of the other 2 sides.

Slope= y^2-y^1
————
x^2-x^1
slope= 12-0
——-
6+2
slope= 12
—-
8
slope= 3/2
perpendicular slope is the opposite reciprocal
perpendicular slope= -2/3
Answer:
The proportion is 2/7 = 12/42
x = 12
The answer is 12
