The sum of two sides has to be bigger than the third side to form a triangle

Applying the Triangle Inequality Theorem, we can see that 10 + 2 ≯ 30 10+2\ngtr 30 . Therefore, this triangle's area is 0 0 , or also that it has no area.

We know that the difference between any two sides in a triangle should be less than the third side.But according to the given statement the difference between 30 and 20 is 10, but the third side is 10.Since it is not less than 10, therefore the triangle with sides 10,20 and 30 does not form.So the area of the triangle is 0
