Understanding Perimeter

The video tutorial explains the concept of perimeter, defining it as the shortest distance around a figure. It discusses how perimeter can be measured using rulers and grid paper, and provides real-life examples such as measuring the perimeters of roofs, windows, and walls. The tutorial includes a step-by-step guide on calculating perimeter using grid paper, with examples demonstrating the process. The video concludes with a call to action for viewers to like and subscribe for more content.

What is the perimeter of a shape?

• The longest distance around a figure

• The shortest distance around a figure

• The volume of a figure

• The area of a figure

Why can't a rope be used to measure the perimeter of a rectangle?

• Because it measures the area

• Because it does not measure the shortest distance

• Because it measures the shortest distance

• Because it measures the longest distance
