Question

The smaller rectangle is a 1/4 scale drawing of the original figure. Use the drop-down menus to show the missing dimensions of the scaled figure.

Answer 1

To find the missing actual dimension with a scale factor of 1:4 and a known scale dimension, you multiply the scale dimension by the scale factor using a proportion.

Step-by-step explanation:

The question involves using scale factors to find missing dimensions of a scaled figure in geometry.

When the scale factor is given, and one of the dimensions of the scaled figure is known, you can find the missing actual dimension by setting up a proportion.

For example, if you have a scale factor of 1:4 and a known scale dimension of 4 (units), you would use the proportion 1/4 = 4/x. Solving for x gives you the actual dimension corresponding to the scale dimension of 4. You multiply the scale dimension by the scale factor to get the actual dimension.
