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=
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 width

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

Step3: Calculate the actual area

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

Answer:

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