Finding Perimeter and Side Lengths

The video tutorial focuses on understanding perimeter and finding missing side lengths in squares and rectangles. It begins with an introduction to the concept of perimeter and the learning target. The teacher explains how to find missing sides in rectangles by using given perimeter values and applying the properties of rectangles. The tutorial then shifts to squares, demonstrating how to use guess and check methods to find side lengths when the perimeter is known. The video concludes with a summary and encourages students to practice the concepts learned.

What is the learning target for today's lesson?

• To determine the diameter of a circle

• To calculate the volume of a cube

• To find the lengths of missing sides when given the perimeter of a square or rectangle

• To find the area of a circle

When given the perimeter of a rectangle, what is the first step to find the missing sides?

• Multiply all sides together

• Add all sides together

• Divide the perimeter by four

• Subtract known sides from the perimeter

In the example with a perimeter of 26, what is the length of the known side?

• 8

• 12

• 5

• 10

How do you determine the length of the opposite side in a rectangle?

• It is always half of the perimeter

• It is the same as the given side

• It is double the given side

• It is always 10

What is the sum of the two known sides in the rectangle example?

• 8

• 16

• 10

• 20

After subtracting the sum of the known sides from the perimeter, what is the next step?

• Divide the result by two

• Multiply the result by four

• Add the result to the known sides

• Subtract the result from the known sides

What is the length of each of the two missing sides in the rectangle example?

• 4

• 5

• 6

• 7

What is the perimeter of the square in the example?

• 22

• 16

• 18

• 20

What method is suggested to find the side length of a square when given the perimeter?

• Guess and check

• Trial and error

• Multiply by four

• Divide by three

If the side length of a square is guessed to be 3, what is the total perimeter?

• 9

• 15

• 18

• 12
