Answer
30$in^{2}$
Work Step by Step
A circle is inscribed in a triangle having sides of length 5in, 12in 13 in
the length of the radius of the inscribed circle is 2 in.
We need to find the area of the triangle
Where P represents the perimeter of a triangle and r represents the length of the radius of its inscribed circle, the area of the triangle is given by
A = $\frac{1}{2}$rP
Perimeter of triangle = 5+ 12+ 13= 30 in
A = $\frac{1}{2}$rP
A = $\frac{1}{2}$*2* 30= 30$in^{2}$
