Scale & Scale Drawings

Front

What is the scale factor?

Back

The scale factor is a number that scales, or multiplies, a quantity. It is used to determine the ratio of the dimensions of a scale drawing to the actual object.

Front

If a scale drawing uses a scale of 2 inches : 1 foot, how do you convert inches in the drawing to feet in reality?

Back

To convert inches in the drawing to feet in reality, divide the number of inches by 24 (since 1 foot = 12 inches and the scale is 2 inches for every 1 foot).

Front

What is the actual distance if the map scale is 1 in:100 mi and the distance on the map is 1 3/4 inches?

Back

The actual distance is 175 miles (1.75 inches x 100 miles/inch = 175 miles).

Front

How do you find the scale factor between two similar shapes?

Back

To find the scale factor, divide the length of a side of the larger shape by the corresponding side of the smaller shape.

Front

What is the scale factor if the perimeter of a rectangle increases from 20 inches to 80 inches?

Back

The scale factor is 4 (80 inches / 20 inches = 4).

Front

What does a scale drawing represent?

Back

A scale drawing represents an object or area at a specific ratio to its actual size, allowing for a smaller, manageable representation.

Front

If a bakery in a scale drawing measures 104 inches, how do you find its actual size using a scale of 2 inches : 1 foot?

Back

To find the actual size, divide the drawing measurement by 2 to convert inches to feet: 104 inches / 2 = 52 feet.

Front

What is the purpose of using scale drawings?

Back

Scale drawings are used to create accurate representations of objects or areas that are too large or too small to be drawn at actual size.

Front

How do you calculate the actual distance between two points on a map?

Back

Multiply the distance on the map by the scale factor to find the actual distance.

Front

What is a common scale used in maps?

Back

A common scale used in maps is 1 inch : 100 miles, meaning 1 inch on the map represents 100 miles in reality.
