Use Heron's formula to calculate the area
HERON”S FORMULA

Area of Triangle = sqrt%28s%2A%28s-a%29%28s-b%29%28s-c%29%29
where s = half the perimeter a,b,c are the sides of the triangle
A = 12 b= 14 c= 18

S= %28a%2Bb%2Bc%29%2F2 S= 22

Area =
Area =sqrt%28%0922%09%2A%09%28+%0910%09%29%28%098%09%29%28%094%09%29%29

Area =sqrt%28%097040%09%29%29
Area = 83.9 square units
