Measuring Perimeter and Area Concepts

The video tutorial explains the concepts of area and perimeter, using examples like a yard and a fence to illustrate these measurements. It discusses the importance of choosing appropriate units, such as those from the metric or customary systems. The video introduces the tiling strategy for calculating area and perimeter, demonstrating how to divide shapes into unit squares and count them. Tips for accurately calculating these measurements are also provided, emphasizing the use of marks to keep track of counted squares.

What does the grass in the example represent?

• The length of the yard

• The width of the yard

• The perimeter of the yard

• The area of the yard

Which of the following is NOT a unit of measurement for length in the metric system?

• Millimeters

• Yards

• Centimeters

• Meters

How is area measured?

• In cubic units

• In circular units

• In linear units

• In square units

What is the area of a rectangle with 12 unit squares each measuring 1 yard by 1 yard?

• 12 cubic yards

• 12 linear yards

• 12 yards

• 12 square yards

What is the strategy called that involves dividing a shape into squares to measure area?

• Gridding

How is perimeter measured?

• In circular units

What is the perimeter of a rectangle with 14 unit squares each measuring 1 yard by 1 yard?

• 14 linear yards

• 14 square yards

• 14 yards

When measuring perimeter, why might a square be counted twice?

• Because it is a special square

• Because it is in the center of the shape

• Because it has two edges on the perimeter

• Because it is larger than other squares

• Count out loud

• Place a mark on each counted edge

• Use a calculator

• Use a ruler
