Using Scale Factors to Find the Area of Scale Drawings

The video tutorial explains how to calculate the scaled area of a figure using a scale factor. It begins by defining a scale factor and demonstrating its effect on the dimensions of a figure. The tutorial then shows that simply multiplying the original area by the scale factor does not yield the correct scaled area. Instead, the scaled area is calculated by multiplying the original area by the square of the scale factor. The video provides examples and derives the formula for scaled area, emphasizing the importance of using the scale factor squared.

What is the relationship between the original area and the scaled area when using the scale factor squared?

Provide an example of calculating the scaled area using a scale factor of 8.

Why is it incorrect to multiply the original area by the scale factor alone to find the scaled area?
