You can put this solution on YOUR website!
The area of the inside new triangle is 1/4 the area of the larger one.
You can show this by using the theorem that says when you connect midpoints of sides of a triangle, that new segment is parallel to the third side and half its length. If you do that to all three pairs, you generate a triangle completely similar to the first but 1/2 its dimensions, thus 1/4 its area.
