Area of a Rectangle and Square

The video tutorial explains how to calculate the perimeter and area of squares and rectangles. It introduces the concept of area as the space a shape covers and demonstrates measuring area using small squares. The tutorial provides methods to calculate the area of rectangles by multiplying length and breadth, and the area of squares by squaring the side length. It also uses a square grid to find the area of various shapes and concludes with a recap of important points about area measurement.

What is the perimeter of a rectangle?

• The area of the rectangle

• The length of one side

• The width of the rectangle

• The total length of all four sides

How can we determine if one shape covers more space than another?

• By measuring the height

• By measuring the perimeter

• By counting the number of red squares needed to cover it

• By looking at the shape

What is the area of a shape if it is covered by 16 red squares, each 1 cm squared?

• 32 square centimeters

• 4 square centimeters

• 8 square centimeters

• 16 square centimeters

How do you calculate the area of a rectangle?

• Subtract the width from the length

• Multiply the length by the width

• Divide the length by the width

• Add the length and the width

If a square has sides of 4 cm, what is its area?

• 12 square centimeters

• 20 square centimeters

• 8 square centimeters

• 16 square centimeters

What is the area of a rectangle that covers 6 squares on a grid?

• 9 square centimeters

• 12 square centimeters

• 6 square centimeters

• 3 square centimeters

What should be the unit of area if the sides are measured in meters?

• Cubic meters

• Square meters

• Centimeters

• Meters
