Understanding Area Calculation

The video tutorial explains how to find the area of a red rectangle within a larger blue rectangle. It begins by identifying the known lengths and uses subtraction to find the missing lengths. The area is then calculated by multiplying the length and width of the red rectangle, resulting in 48 square units. The tutorial concludes with a helpful note.

What is the initial length of the red rectangle mentioned in the problem?

• 6

• 8

• 10

• 12

How do you determine the missing length of the red rectangle?

• By multiplying the lengths of the blue rectangle

• By dividing the total length of the blue rectangle by two

• By subtracting the known lengths from the total length of the blue rectangle

• By adding the lengths of the blue rectangle

What is the length of the missing side of the red rectangle?

• 6

• 4

• 7

• 5

What formula is used to calculate the area of the red rectangle?

• Length minus width

• Length times width

• Length plus width

• Length divided by width

What is the final area of the red rectangle?

• 48 square units

• 42 square units

• 36 square units

• 54 square units
