Answers: 2
. If the area of the triangle is 25.5 square centimeters, then you can find the lengths of the sides of the triangle. Since the area of a triangle is the base multiplied by the height and then divided by 2, the side lengths of the triangle must be 
. This means that the hypotenuse of the triangle must be 
, or a little over 10cm. Therefore, the answer I would pick is choice D. Hope this helps!
