Step 1: Calculate the semi perimeter of the triangle.

NOTE: First calculate the perimeter of a triangle by adding up the length of

its three sides. Then, multiply by \frac {1}{2}

EXAMPLE: \frac{1}{2} (a+b+c)

\frac {1}{2}{(3+4+5)}

s={\frac {1}{2}}(12) = 6

Step 2: Substitute the values of semi perimeter and lengths of the triangle in the area formula

FORMULA: Area=\sqrt{s(s-a)(s-b)(s-c)},

EXAMPLE:

Area = \sqrt {6(6-3)(6-4)(6-5)}

Step 3: Calculate the values in parentheses.

Step 4: Multiply the two values under the radical sign.Then, find their square root.
