Formula to find area of triangle is
{tex}A= \sqrt{s(s - a)(s - b)(s - c)}{/tex}
Where, s is the semi perimeter,
{tex}s=\frac{a+b+c}{2}{/tex}
a=3 ,b=4, c= 5 cm sides of the triangle
Substituting in the formula,
{tex}s=\frac{3+4+5}{2}{/tex}
{tex}s=\frac{12}{2}{/tex}
s=6
{tex}A= \sqrt{s(s - a)(s - b)(s - c)}{/tex}
{tex}A=\sqrt{6(6 - 3)(6 - 4)(6 - 5)}{/tex}
{tex}A= \sqrt{6 \times 3 \times 2 \times 1}{/tex}
{tex}A= \sqrt{36}{/tex}
{tex}A= 6 cm^2{/tex}
Therefore, The area of the triangle is 6 centimeter square.
