Lesson Summary:

In this lesson, students are taught how to use dilations and factors to find the new perimeter and area of a rectangle. The teacher explains how to find the original perimeter and area of a rectangle, and then shows how to use a factor of six to determine the new perimeter and area of the same rectangle. The teacher emphasizes the importance of correctly squaring the factor and provides a visual aid to help students understand the concept.

How to use dilations and factors to find the new perimeter and area of a rectangle

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.
