Scale Drawings Flashcard

Front

What is a map scale?

Back

A map scale is a ratio that represents the relationship between a distance on the map and the actual distance it represents in real life.

Front

If a map scale indicates that \( \frac{1}{4} \) inch equals 10 miles, how many miles does 1 inch represent?

Back

40 miles

Front

What does a scale of 1 inch to 20 feet mean in a blueprint?

Back

It means that every 1 inch on the blueprint corresponds to 20 feet in actual length.

Front

If a blueprint shows a building length of 9 inches, what is the actual length if the scale is 1 inch to 20 feet?

Back

180 feet

Front

What is the formula to calculate the actual distance using a map scale?

Back

Actual Distance = Distance on Map × Scale Factor.

Front

If a model car is made at a scale of 1 ft : 24 inches, how do you find the model's length if the actual car is 192 inches long?

Back

Convert the actual length to feet (192 inches = 16 ft) and then use the scale to find the model length (16 ft ÷ 24 = 0.67 ft or 8 ft).

Front

What is the actual distance between two cities if they are 3 inches apart on a map with a scale of 1 inch to 5 miles?

Back

15 miles

Front

How do you calculate the perimeter of a rectangular plot of land from a scale drawing?

Back

Perimeter = 2 × (Length + Width). Use the scale to convert cm to actual meters.

Front

If a rectangular plot measures 3 cm by 5 cm on a scale of 1 cm to 30 meters, what is the actual perimeter?

Back

480 meters

Front

What is the relationship between scale drawings and real-life dimensions?

Back

Scale drawings are proportional representations of real-life objects, allowing for accurate measurements and comparisons.
