Yes.
Use the Hero's formula: Let s = (a + b + c)/2. Then the area of the triangle equals√[s(s - a)(s - b)(s - c)], where a, b, and c denote the sides of the triangle.
No, the formula is far from simple - requiring elliptical integrals.
Divide the polygon into triangles. Calculate the areas of the triangles and then sum these.
half of the base multipled by the height
Half of the base times height.
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
Heron's formula can be derived by dividing a triangle into two right triangles and applying the Pythagorean theorem to each. This allows for the expression of the area of a triangle in terms of its side lengths, which eventually leads to Heron's formula.

The title of the formula is "Formula for the Area of a Triangle". No discrimination is expressed or implied.

True. This is because the slant height of an oblique cone cannot be defined.
Divide the polygon into triangles. Calculate the areas of the triangles and then sum these.
Area of the right section x Length of the lateral edge
half of the base multipled by the height
Half of the base times height.
A=1/2 base x height
There are very many formulae depending on what information you have.
