So we're going to use a couple different formulas to answer this question.
00:03
The first is the area of a right triangle, which is a equals one -half base times height, or i should say the area of any triangle.
00:12
So we know that the area is equal to 270 meters, and we know that the height is equal to 15 meters.
00:22
So we can kind of plug those both in and then solve for the base.
00:25
We are trying to find the hypotenuse.
00:27
We're not going to get that here, but we'll get essentially the other.
00:30
Leg of the triangle where the height is one, the base is the other, and then we can use the pythagorean theorem to find the hypotenuse.
00:36
So in order to solve this, we're first going to divide each side by 15, leaving us with 18 is equal to one -half b, and then we will multiply by the reciprocal of one -half, which is two, leaving us with b is equal to 36...
