Question

A garage floor measures 150 feet by something. A scale drawing of the floor on grid paper uses a scale of 1 unit : 15 feet. What are the dimensions of the drawing?

a. 10 units by 10 units
b. 15 units by 15 units
c. 10 units by 1 unit
d. 1 unit by 1 unit

Answer 1

The dimensions of the drawing are 10 units by something.

Step-by-step explanation:

The scale factor for the drawing is 1 unit : 15 feet. To find the dimensions of the drawing, you can use the scale factor to determine the length and width of the floor in units. The length of the floor in units would be 150 feet divided by the scale factor, which is 10 units. Therefore, the dimensions of the drawing are 10 units by something. The answer choice that matches this is a. 10 units by 10 units.
