Respuesta :

First we need to find the semi-permiter

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

where a,b,c are the sides of the triangle

a=15

b=16

c=13

[tex]s=\frac{15+16+13}{2}=22[/tex]

Then we will use the Heron's formula in order to find the area of the triangle

[tex]A=\sqrt[]{s(s-a)(s-b)(s-c)}[/tex]

then we substitute the values

[tex]undefined[/tex]
