Question

Determine whether a triangle can be formed with the given side lengths. If so, use Heron's formula to find the area of the triangle.

a = 240
b = 132
c = 330

Answer 1

see if sum of any two sides > third side.

Answer 2

2s=a+b+c
\[area of \triangle=\sqrt{s \left( s-a \right)\left( s-b \right)\left( s-c \right)}\]
now you can solve.
