area = SQRT((peri(peri-side1)(peri-side2)(peri-side3)))

Where perimiter ,

peri = (side1+side2+side3)/2

Python Code

# Python Program to find the area of triangle

side1 = 2
side2 = 1
side3 = 8

# calculate the semi perimeter in Python
peri = (side1 + side2 + side3) / 2

# calculate the area of a triangle
areaTriangle = (peri*(peri-side1)*(peri-side1)*(peri-side1)) ** 0.5

print('The area of the triangle is %0.2f' %areaTriangle)


The area of the triangle is 15.36
