Question

The area of a triangle is found using the following formula:

Answer 1

Options?

Answer 2

There are 2 formula's for that:

If the base and height is known then:

\[A = \frac{ 1 }{2 } \times base \times height\]

And if the length of the 3 sides of the triangles is known than:

Let side1 be a
side2 be b
and side 3 be c
\[Area \Delta = \sqrt{s(s-a)(s-b)(s-c)}\]

where s is the semi perimeter of the triangle:

\[s = \frac{ a +b +c }{ 2}\]

This method is called heron's method

Answer 3

ANd is base and height is known the diagram will be:
