Hi,
Area of a triangle with sides: 12cm, 13cm and 5cm
*Note: Heron's Equation will find the area of a triangle when 3 sides are given
 
A={{{sqrt(s(s-a)(s-b)(s-c))}}} where s is the semi-perimeter in this case s =30/2cm = 15cm
A={{{sqrt(15(15-12)(15-13)(15-5))}}} 
A={{{sqrt(15(3)(2)(10))}}}
A={{{sqrt(900)}}}
A= 30cm^2
