Question

You are a stone sawyer. The scale drawing you are using to cut paving stones for a driveway shows a measurement 2 inches wide and 4.5 inches long. You are going to cut stones 18 inches long. How wide do they need to be?

Answer 1

The actual width of cut stones is 8 inches

Explanation:

The scale drawing you are using to cut paving stones for a driveway shows a measurement 2 inches wide and 4.5 inches long.

Scale drawing length = 4.5 inches

Scale drawing breadth = 2 inches

Actual length = 18 inches

Let x be the actual width

So,
`(4.5)/(2)=(18)/(x)`

`x=(18 * 2)/(4.5)`

x=8

Hence the actual width of cut stones is 8 inches
