In triangle ABC,AB=10,AC=7 and BC=8
How do we need to slide out along AB so that the area of the overlapping region(the shaded triangle A'BD) is half the area of triangle ABC?

Since the height would not change, the base of the shaded triangle, which we can't see,
has to be 5 units to be half the original triangle.
remember : area of triangle = (1/2)(base)(height)
