For this problem, we are finding the area of this triangle.
00:05
This triangle has sides 16, 20, and 26.
00:10
My recommendation is to use huron's formula.
00:14
This formula is excellent for finding areas of triangles if you know all three side lengths, which we do.
00:22
This is the formula.
00:23
You take the square root of the semi -perumina times the semi -priminar minus one side times the semi -perimeter minus the second side, times the semi -parimeter minus the third side.
00:37
Now you may ask, what is the semi -perimeter? the semi -permiter is basically half of the perimeter.
00:44
So that's going to be our first thing that we need to do.
00:47
Find the perimeter of this particular triangle, then find a semi -perimeter, and then we can stick everything into the formula.
00:56
So let's find the perimeter.
00:58
Perimeter is where you take all three sides, and then add them together.
01:02
So 16 plus 20 plus 26.
01:06
I got 62.
01:10
So the semi -perimeter is going to be half of that.
01:14
Semi -perimeter equals half of 62, which is 31.
01:21
So that's going to be our s...
