Question

what number can you multiply each length in the scale drawing by to find the actual length?
what are the actual length and width of the trampoline?
actual length = ft
actual width = ft

Explanation:

Step1: Use the scale factor

The scale is \(1\) in. : \(3\) ft. So we multiply the scale - drawing length and width by \(3\) to get the actual length and width.

Step2: Calculate the actual length

Given the scale - drawing length \(l = 4\) in.
Actual length \(=4\times3\)
\(= 12\) ft

Step3: Calculate the actual width

Given the scale - drawing width \(w = 2\) in.
Actual width \(=2\times3\)
\(=6\) ft

Answer:

Actual length \( = 12\) ft
Actual width \(=6\) ft
