Finding the Perimeter of Squares and Rectangles

This video tutorial teaches how to find the perimeter of squares and rectangles by adding side lengths. It explains the concept of equal side lengths, differentiates between area and perimeter, and provides methods for calculating perimeter using number sentences and mental math. The tutorial includes examples for both rectangles and squares, emphasizing the importance of understanding side lengths and avoiding common mistakes.

What is the main difference between area and perimeter?

• Area is the distance around a shape, while perimeter is the space inside.

• Area is the space inside a shape, while perimeter is the distance around it.

• Area and perimeter are the same.

• Perimeter is always larger than area.

If one long side of a rectangle is 5 units, what is the length of the opposite long side?

• 2 units

• 5 units

• 10 units

• It cannot be determined

How can you calculate the perimeter of a rectangle using mental math?

• Double the long side, double the short side, and add them together.

• Double the length of one side.

• Add all side lengths together.

• Multiply the length of one side by four.

In a square, if one side is 3 units, what is the perimeter?

• 6 units

• 9 units

• 12 units

• 15 units

What is the perimeter of a square garden with each side measuring 4 units?

• 12 units

• 8 units

• 16 units

• 20 units
