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: Determine the scale factor

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 width

Given the width \(w = 2\) in. in the scale drawing. Using the scale \(1\) in. \(=3\) ft, the actual width \(W\) is \(W=2\times3 = 6\) ft.

Step3: Calculate the actual length

Given the length \(l = 4\) in. in the scale drawing. Using the scale \(1\) in. \(=3\) ft, the actual length \(L\) is \(L = 4\times3=12\) ft.

Answer:

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