Understanding Area and Perimeter

The video tutorial by Miss B covers the concepts of area and perimeter in common core math. It begins with a catchy song to help remember the difference between area and perimeter. The tutorial then demonstrates how to calculate the perimeter by counting the outer units of shapes and highlights common mistakes. It proceeds to explain how to find the area by counting the inner units and using the base times height formula. The video emphasizes the importance of understanding the difference between area and perimeter and the necessity of using correct measurement units. The tutorial concludes with a reminder to include measurement units in calculations.

What is the main difference between area and perimeter?

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

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

• Area and perimeter are the same.

• Area is measured in meters, perimeter in centimeters.

When calculating the perimeter, why is it important to count each side, especially at corners?

• Corners are not part of the perimeter.

• Corners can be easily missed, leading to incorrect calculations.

• Corners are counted twice.

• Corners are always longer than other sides.

What is the perimeter of a shape if each side is 1 cm and there are 12 sides?

• 18 cm

• 6 cm

• 24 cm

• 12 cm

How do you find the area of a shape using squares?

• Count the number of squares inside the shape.

• Measure the length of one side.

• Add the lengths of all sides.

• Multiply the perimeter by two.

If a shape's perimeter is 16 cm and its area is 12 square cm, what does this tell us?

• The shape is a square.

• The shape is a rectangle.

• The shape has more perimeter than area.

• The shape has more area than perimeter.

What is the formula for calculating the area of a rectangle?

• Length plus width

• Length times width

• Base times height

• Perimeter divided by two

If a rectangle has a base of 3 cm and a height of 6 cm, what is its area?

• 18 square cm

• 9 square cm

• 12 square cm

• 6 square cm

How do you calculate the area of a shape without a grid?

• Divide the perimeter by two.

• Add the lengths of all sides.

• Use the base times height formula.

• Count the number of sides.

What is the area of a square with a side length of 4 meters?

• 8 square meters

• 16 square meters

• 12 square meters

• 4 square meters

Why is it important to include units when measuring area and perimeter?

• Units are only needed for area, not perimeter.

• Units make the numbers look bigger.

• Units help to understand the scale of measurement.

• Units are not important.
