Finding the Area of a Rectangle Using the Area Formula

This video tutorial explains the concept of area as the total number of unit squares covering a plain figure. It introduces a formula to calculate the area of a rectangle by multiplying its length and width. The tutorial uses an example of a rectangle covered by unit squares to demonstrate the calculation process. It further tests the formula with a specific rectangle, confirming the result by counting unit squares on a grid. The lesson concludes by summarizing the formula for calculating the area of a rectangle.

What is the area of a rectangle if it is covered by 4 rows of 8 unit squares?

• 24 square units

• 40 square units

• 32 square units

• 16 square units

How do you calculate the area of a rectangle using its sides?

• Multiply the length by the width

• Subtract the width from the length

• Add the length and width

• Divide the length by the width

If a rectangle has a length of 8 cm and a width of 6 cm, what is its area?

• 50 square centimeters

• 48 square centimeters

• 46 square centimeters

• 42 square centimeters

What unit is used to measure the area of a rectangle in the given example?

• Square centimeters

• Square inches

• Square feet

• Square meters

How can you verify the area of a rectangle calculated using the formula?

• By using a ruler to measure the sides again

• By measuring the perimeter

• By placing it on a grid and counting the squares

• By comparing it to another rectangle
