Scale Drawings and Area Calculations

This video tutorial covers the concept of scale drawings, using examples like the Westerlund Lysander aircraft, a building blueprint, and a map of Lafayette Square. It explains how to estimate actual dimensions from scale drawings and maps. Additionally, it discusses creating a scaled copy of a triangle and analyzing its area and dimensions.

What is the approximate wingspan of the Westerlund Lysander based on the scale drawing?

• 40 feet

• 55 feet

• 45 feet

• 50 feet

How tall is the Westerlund Lysander according to the scale drawing?

• 12 feet

• 10 feet

• 14 feet

• 16 feet

What is the length of the Westerlund Lysander in meters as per the scale drawing?

• 9 meters

• 7 meters

• 8 meters

• 10 meters

If a room on a blueprint measures 3 inches by 5.5 inches, what are its actual dimensions?

• 25 feet by 50 feet

• 35 feet by 60 feet

• 20 feet by 45 feet

What is the area of the original triangle A?

• 3.5 square units

• 4.5 square units

• 5.5 square units

• 6.5 square units

How many times larger is the area of the scaled copy of triangle A compared to the original?

• 10 times

• 14 times

• 12 times

• 16 times

What scale factor was used to create the scaled copy of triangle A?
