Scale & Scale Drawings

Front

What is a scale drawing?

Back

A scale drawing is a representation of an object or area that is proportionally reduced or enlarged to fit a specific scale, allowing for accurate representation of dimensions.

Front

What does the term 'scale factor' mean?

Back

The scale factor is the ratio of a length in a scale drawing to the corresponding length in the actual object. It indicates how much the drawing has been enlarged or reduced.

Front

How do you calculate the perimeter of a shape in a scale drawing?

Back

To calculate the perimeter of a shape in a scale drawing, first find the lengths of all sides in the drawing, then multiply each length by the scale factor to find the actual lengths, and finally sum these actual lengths.

Front

If a scale drawing uses a scale of 1 inch : 5 feet, how would you convert 15 feet to inches in the drawing?

Back

To convert 15 feet to inches in the drawing, divide 15 by 5 (the scale factor), which equals 3 inches.

Front

What is the actual distance if a map scale is 1 inch : 50 miles and the distance on the map is 3 inches?

Back

The actual distance is 3 inches x 50 miles/inch = 150 miles.

Front

How do you find the height of an object in a scale drawing?

Back

To find the height of an object in a scale drawing, divide the actual height by the scale factor.

Front

What is the formula for finding the area of a shape in a scale drawing?

Back

The area in the scale drawing can be found by calculating the area using the dimensions in the drawing and then multiplying by the square of the scale factor to find the actual area.

Front

If a tent is 6 feet wide in reality and the scale is 1 inch : 3 feet, how wide is it in the drawing?

Back

The width in the drawing is 6 feet / 3 feet/inch = 2 inches.

Front

What is the significance of understanding scale in real-world applications?

Back

Understanding scale is crucial for accurately interpreting maps, architectural plans, and models, ensuring that representations are proportional and can be used for practical purposes.

Front

How do you determine the scale factor from a scale drawing to the actual object?

Back

To determine the scale factor, divide the actual measurement by the corresponding measurement in the scale drawing.
