Thread: Finding Area Problem

1. 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.

4. try

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

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