Question

A scale drawing of Valerie's garden uses a scale of 2 inches = 5 feet. If the garden's width on the scale drawing measures 3 inches, what is the actual width, in feet, of Valerie's garden?

Answer 1

The actual width of Valerie's garden is 7.5 feet.

Explanation:

This question can be solved using a rule of three.

The scale is that 2 inches in the drawing is 5 feet of actual measure.

The width measures 3 inches in the drawing, so the actual measure is:

2 inches - 5 feet

3 inches - x feet

2x = 3*5

2x = 15

x = 15/2

x = 7.5

The actual width of Valerie's garden is 7.5 feet.
