Calculating Perimeters of Shapes

The video tutorial explains how to find the perimeter of various geometric shapes, including triangles, squares, and complex figures. It provides examples and real-world applications, such as calculating the amount of fencing needed for a garden or tape for a pool. The video concludes with a suggestion for viewers to practice finding the perimeter of their room.

What is the perimeter of a geometric figure?

• The area of the figure

• The difference between the longest and shortest sides

• The volume of the figure

• The sum of the lengths of its sides

How do you calculate the perimeter of a triangle with sides measuring 12, 14, and 10 inches?
