This video includes key concepts, notation, and vocabulary such as: scale factor (the constant of proportionality, k, between two similar objects); and the formula, scaled area equals k squared times original area.

Before watching this video, you should already be familiar with area of shapes, the notation for “k squared”, and the equation Quantity = Percent x Whole.

After watching this video, you will be prepared to solve more advanced word problems involving scale factors and percents.
