Finding the Perimeter of Rectangles

This video tutorial teaches how to find the perimeter of a rectangle using area models. It begins with an introduction to the concept of perimeter and a review of rectangle properties. The tutorial provides an example of calculating the perimeter using unit squares and clarifies the difference between area and perimeter. Finally, it demonstrates how to calculate the perimeter of a rectangular walking track.

What is the first step in finding the perimeter of a rectangular walking track?

• Calculate the area of the track.

• Place unit squares along the edges of the rectangle.

• Measure the diagonal of the rectangle.

• Count the number of corners in the rectangle.

Which of the following is true about rectangles?

• They have no right angles.

• They are always squares.

• Opposite sides are congruent and parallel.

• All sides are of different lengths.

How do you represent the length of a rectangle using unit squares?

• By placing squares only on one side.

• By placing squares along the length inside the rectangle.

• By placing squares along the diagonal.

• By placing squares randomly inside the rectangle.

What is the perimeter of a rectangle with a length of 4 yards and a width of 3 yards?

• 18 yards

• 16 yards

• 14 yards

• 12 yards

What is the main difference between area and perimeter?

• Area is the total distance around a figure, while perimeter is the space within.

• Perimeter is always larger than area.

• Area is the space within a figure, while perimeter is the total distance around it.

• Area and perimeter are the same.

How do you find the perimeter of a rectangle with a length of 12 feet and a width of 9 feet?

• By adding the length and width and multiplying by 2.

• By multiplying the length and width.

• By dividing the length by the width.

• By subtracting the width from the length.

What is the perimeter of a rectangular walking track that is 12 feet long and 9 feet wide?

• 48 feet

• 30 feet

• 36 feet

• 42 feet

Why is it important to count only the outer line segments when calculating perimeter?

• Because they are easier to count.

• Because they are always longer than the inner segments.

• Because they represent the total distance around the figure.

• Because they represent the total space within the figure.

What is the unit of measurement for the perimeter in the example with a length of 4 yards and a width of 3 yards?

• Yards

• Feet

• Inches

• Meters
