Perimeter and Basic Arithmetic Concepts

Matt and Mr. J explain how to find the perimeter of a figure by first identifying missing side lengths. They demonstrate how to calculate these missing measurements and then add all the side lengths together to find the total perimeter, which is 40 inches. The video concludes with a summary of the process.

What is the perimeter of a figure?

• The diagonal of the figure

• The volume of the figure

• The distance around the figure
