Using Perimeter to Find the Sides' Lengths (Part 2)

The video tutorial explains how to find the missing side lengths of a rectangle when given its perimeter and one side length. It starts by introducing the problem and the known values, then explains the concept of perimeter as the sum of all side lengths. The tutorial demonstrates substituting known values into the perimeter equation and solving for the unknown side lengths using subtraction. Finally, it concludes by summarizing the steps taken to solve the problem and reinforcing the concept of equal opposite sides in a rectangle.

What is the perimeter of a shape?

• The length of one side

• The sum of all side lengths

• The area of the shape

• The difference between the longest and shortest sides

If the top side of a rectangle is 8 inches, what is the length of the bottom side?

• 4 inches

• 12 inches

• 8 inches

• 16 inches

How do you find the total length of the right and left sides of a rectangle?

• Multiply the length of one side by four

• Add the lengths of the top and bottom sides

• Subtract the sum of the top and bottom sides from the perimeter

• Divide the perimeter by two

What operation is used to find the length of one side when the total of two equal sides is known?

• Subtraction

• Multiplication

• Addition

• Division

If the total length of the right and left sides is 12 inches, what is the length of one side?

• 3 inches

• 6 inches

• 12 inches

• 9 inches
