Review: Perimeter and Area

The video tutorial explains how to calculate the perimeter and area of shapes, specifically squares and rectangles. It begins by defining perimeter as the total distance around a shape and demonstrates how to calculate it by adding the lengths of the sides. The tutorial then contrasts perimeter with area, which measures the surface inside a shape, and explains how to calculate area by multiplying the length and width. Examples are provided to illustrate these concepts, emphasizing the difference between linear and square measurements.

How do you calculate the perimeter of a square if one side is 4 inches?

• Multiply 4 by 3

• Add 4 four times

• Add 4 two times

• Multiply 4 by 2

What is the main difference between perimeter and area?

• Perimeter is for 3D objects, area is for 2D objects

• Perimeter is always larger than area

• Perimeter is the distance around, area is the space inside

• Perimeter is measured in square units, area is not

How is the area of a rectangle calculated?

• By adding all the sides

• By adding the length and width

• By multiplying the length by the width

• By multiplying the length by 2

If a square has a side length of 6 inches, what is its area?

• 12 square inches

• 48 square inches

• 36 square inches

• 24 square inches

What is the perimeter of a rectangle with a length of 15 inches and a width of 7 inches?

• 44 inches

• 30 inches

• 22 inches

• 52 inches
