Relating Area and Multiplication: Composing Rectangles

This video tutorial teaches how to relate area and multiplication by composing rectangles. It begins with an introduction to unit squares and how they form the basis of calculating area. The lesson progresses to demonstrate how to combine rectangles with similar widths to find the total area, using examples to illustrate the process. The tutorial concludes with a recap of the key concepts covered.

What is the area of a rectangle that has 2 rows and 3 unit squares in each row?

• 6 unit squares

• 5 unit squares

• 8 unit squares

• 9 unit squares

If you have two rectangles, one with an area of 6 square units and another with 8 square units, what is their combined area?

• 15 square units

• 14 square units

• 13 square units

• 12 square units

How many unit squares are there in a rectangle with 3 rows and 4 unit squares per row?

• 10 unit squares

• 11 unit squares

• 12 unit squares

• 13 unit squares

What is the total area when combining two rectangles, one with 12 square units and another with 15 square units?

• 25 square units

• 27 square units

• 28 square units

• 26 square units

When combining two rectangles with similar widths, if one has 2 rows and 3 unit squares, and the other has 2 rows and 4 unit squares, what is the total area?

• 14 square units

• 15 square units

• 13 square units

• 12 square units
