Hj bisects ihl, hk bisects jhl, and ihk = 51. find ihl.

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

           

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

The correct answer is $90
