Median of a triangle means a line segment from a vertex of a triangle to opposite side which divides the opposite side in two equal parts. there can be maximum three medians in a triangle. The point of intersection of medians of triangle is called centroid.
As we know median of a triangle divides it into two triangles of equal area.So Ar (IHJ) = Ar (HJL) = 51 ∴ ( HJ IS THE MEDIAN)
Now HK is the median of JHL.
So,Ar (HKL) =Ar (HKJ) = 51÷2 =25.5
