As we can see the triangle ABC is a right angled triangle
It’s sides follow Pythagoras theorem
(13)^2=(12)^2+(5)^2
169=144+25
169=169. -(i)
Let the triangle’s right angle be angle ABC ie “B”
As we know median from a vertice to opposite side divides it into two equal parts
As shown in picture below
Now in triangle ABP
Angle B=90
AB=5 & BP=6
By Pythagorean’s triplets
AP^2=AB^2*BP^2
AP ^2 = 5^2+6^2
=. 25+36
=61
AP = root 61 ie 7.81
By rounding the figure of 7.81 we can say that AP=8 cm
And from your options it would be (B)
I suppose
Hope this helped you :)
