So in this question they're asking us what is the side length of an equilateral triangle.
00:05
Let's assume that this is the equilateral triangle here.
00:08
Let's say this is abc.
00:10
So each side of an equilateral triangle has the same side length for all sides.
00:35
So that is something that we need to know.
00:37
That a triangle that has equal side lengths, so ab should be equal to bc should be equal to ca.
00:43
In that case you would call that to be an equilateral triangle.
00:48
So they've given us the perimeter of this triangle abc.
00:52
The perimeter is equal to 36 2 by 3.
01:00
36 2 by 3.
01:02
36 2 by 3, well in terms of inches, the unit they've given us is in inches.
01:11
So i'm converting 36 2 by 3, it's a mixed fraction...
