You can find the area of any triangle by:
Where b = the length of the base and h = the height of the triangle.
It doesn't matter which leg you call the base, so we'll say and , so...

square miles.
To find the perimeter, you'll need to know the length of the hypotenuse of the right triangle. Use the Pythagorean theorem: where: , , and is the length of the hypotenuse.
Evaluate.

Take the square root of both sides.
So the length of the hypotenuse = 41 miles.
Now you can add the three sides to get the perimeter P.
=miles.
