Calculating Area Using the Distributive Property

The video tutorial explains how to calculate the area of a rectangle using two methods: multiplying the length by the width and dividing the rectangle into sub-rectangles. It demonstrates the distributive property by showing that the sum of the areas of the sub-rectangles equals the area of the entire rectangle. The tutorial encourages viewers to pause and try both methods, reinforcing the concept with calculations and verifying the results.

What is the first step to calculate the area of a rectangle?

• Divide the length by the width

• Subtract the length from the width

• Add the length and width

• Multiply the length by the width
