Example Question #13 : How To Find The Area Of A Right Triangle
Find the area of this right triangle:
The area of a triangle is found using the formula . For a right triangle, we can use the two legs as the base and height regardless of the orientation of the triangle.
In this case, we only know one leg, but we can figure out the other by using the Pythagorean Theorem:
subtract 36 from both sides
take the square root
Now that we have our "base" and "height," we can substitute them into the formula and find the area:
