Step-by-step explanation:
Consider the attached figure. The height CD cuts the triangle exactly in half. This means that

Moreover, since CD is the height of the triangle, we know that ACD is a right triangle. We know the hypothenuse AC to be 20 feet because it is a side of the triangle, and we just found out that AD is 10. We can use the pythagorean theorem to deduce

So, the area is
