Finding Perimeter of Shapes

The video tutorial explains how to find the perimeter of a shape formed by given coordinates. It starts by plotting the coordinates on a coordinate plane, which form a rectangle. The tutorial then demonstrates how to calculate the perimeter by adding the lengths of all four sides of the rectangle, resulting in a total perimeter of 18 units.

What is the first step in solving the problem of finding the perimeter of a shape formed by coordinates?

• Measure the angles of the shape

• Identify the type of shape

• Plot the coordinates on a coordinate plane

• Calculate the area of the shape

After plotting the points, what shape do the connected points form?

• Triangle

• Circle

• Rectangle

• Pentagon

What is the length of one of the longer sides of the rectangle?

• 3

• 5

• 9

• 6

How do you calculate the perimeter of a rectangle?

• Multiply the length by the width

• Divide the area by the length

• Add the lengths of all four sides

• Subtract the width from the length

What is the total perimeter of the rectangle formed by the given coordinates?

• 21

• 12

• 15

• 18
