Question

jazlyn owns an. purchase for her facility. the scale is shown in the
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 = 12 ft
actual width = 6 ft
what is the actual area of the trampoline?

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 get the actual length is \(3\).

Step2: Calculate the actual length

Given the scale - drawing length \(l = 4\) in. Using the formula \(Actual\ length=Scale - drawing\ length\times Scale\ factor\), we have \(Actual\ length=4\times3 = 12\) ft.

Step3: Calculate the actual width

Given the scale - drawing width \(w = 2\) in. Using the formula \(Actual\ width=Scale - drawing\ width\times Scale\ factor\), we have \(Actual\ width=2\times3=6\) ft.

Step4: Calculate the actual area

The formula for the area of a rectangle is \(A = length\times width\). Substituting the actual length \(l = 12\) ft and actual width \(w = 6\) ft, we get \(A=12\times6=72\) \(ft^{2}\).

Answer:

The number to multiply is \(3\). The actual length is \(12\) ft, the actual width is \(6\) ft, and the actual area is \(72\ ft^{2}\).
