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 =
actual width =

Explanation:

Step1: Find the multiplier

The scale is \(1\) in. : \(3\) ft. So, the number to multiply each length in the scale drawing by to find the actual length is \(3\).

Step2: Calculate the actual length

The length \(l = 4\) in. in the scale drawing. Using the scale factor, actual length \(=4\times3 = 12\) ft.

Step3: Calculate the actual width

The width \(w = 2\) in. in the scale drawing. Using the scale factor, actual width \(=2\times3=6\) ft.

Answer:

The number is \(3\). The actual length is \(12\) ft and the actual width is \(6\) ft.
