Understanding Ratios in Similar Rectangles

The video tutorial explains how to determine the perimeter of a smaller rectangle given the ratio of areas of two similar rectangles and the perimeter of the larger rectangle. It covers the properties of similar polygons, demonstrating how the ratio of areas relates to the ratio of perimeters. The tutorial uses squares to model these ratios and provides a step-by-step solution to find the missing perimeter using proportions.

What is the given ratio of the areas of the two similar rectangles?

• 5 to 4

• 4 to 5

• 16 to 25

• 25 to 16

If the ratio of the sides of two similar polygons is a to b, what is the ratio of their perimeters?

• a squared to b squared

• b to a

• a to b

• b squared to a squared

How can the ratio of the areas be expressed in terms of the sides of similar polygons?

• a to b

• a squared to b squared

• b to a

• b squared to a squared
