In this lesson, you will learn how to find the length of a side of an equilateral triangle given its perimeter. An equilateral triangle is a triangle where all sides are equal in length. To find the length of the side, you need to use algebra and the definition of perimeter. You can set up an equation by representing the unknown side length with a variable, then adding all the sides to equal the perimeter. You can then solve for the variable using algebraic manipulation.

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
