The video tutorial covers scale drawings, equivalent scales, and calculations involving models and polygons. It explains how to order scale drawings by size, identify equivalent scales, and calculate the actual size of a model airplane. The tutorial also discusses scaling quadrilateral side lengths and perimeters, comparing polygon areas, and determining scale factors between figures.

Which scale drawing is the smallest?

• One inch to one meter

• One inch to one centimeter

• One inch to one foot

• One inch to one yard

Which of the following is equivalent to a scale of one inch to one foot?

• 1 to 15

• 1 to 12

• 1 to 20

• 1 to 10

If a model airplane is 8 inches long at a scale of 1:72, how long is the actual airplane?

• 36 feet

• 72 feet

• 48 feet

• 60 feet
