What is the definition of perimeter as stated in the video?
Perimeter is defined as the total distance around the outside boundary of a shape. In the video's example, this is demonstrated by tracing the full outer edge of a rectangle.
Conditions
- Applies to closed shapes such as the rectangle shown.
- In this video, the example uses feet as the unit of measure.
Reasoning, step by step
- Identify the outer boundary of the shape.
- Trace the entire distance around the outside of the shape.
- Sum the lengths of all the sides to find the total distance.
Example
The narrator defines perimeter as the distance around the outside of a shape, using a rectangle with side lengths of 6 ft and 2 ft.
Common misconceptions
- Confusing perimeter with area, which measures the surface inside the shape rather than the boundary.
