Given: ΔKLM, KL = LM = 13in, KM = 10in. Find: The area of ΔKLM
~~~~~~~~~~~~~~~~~~~~~ 

KLM is isosceles triangle.

Therefore, its median LN drawn from the vertex L is an altitude.

Therefore, the two triangles KNL an KNM are right-angled triangles.

From the triangle KNL the length of the altitude |KN| =  =  = 12.

Then the area of the triangle KLM =  = 60 squared inches.
