Finding the Area of a Rectangle Using Multiplication and Addition

This video tutorial teaches how to find the area of a rectangle using multiplication and addition. It explains the concept of area as the number of square units needed to cover a rectangle and demonstrates how to calculate it using rows and columns. The tutorial addresses common misunderstandings and provides a practical example using a building block table, where the area of different sections is calculated and summed to find the total area. The use of parentheses in mathematical operations is also highlighted.

How can you find the area of a rectangle with side measurements of 3 feet and 7 feet?

• By multiplying 3 by 7
