    Finding Area Problem

    This problem was in my Algebra 2 book, but it resembles a geometry problem so IDK...anyways. The problem is I need to find the area of a triangle that has the 5 and 6 meter legs, and whose hypotenuse is unknown. How do I solve this?

    It seems simple, but I got into so many square roots I think I'm wrong.
    BTW, the answer is 15m squared, but I have to show work so...

    Do you have any other information? It is right-angled? Do you have any angles at all?

    Yes, it has one right angle, but no other angles are given.

    try

     A = \frac{1}{2}\times a\times b \times \sin(C)

    where a and b are your side lengths and C is your angle. You will be very happy with the answer.
