You can put this solution on YOUR website!
Both triangles have the same base 10 cm.
The larger triangle has equal legs of 6 cm.
The smaller triangle has equals legs of x cm, where x%3C6.
You can find the area of the large triangle but you cannot find the area of the small triangle so you can't find the shaded region which is the difference in area of the two triangles.
You need more information to solve.
