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 = 12 ft
actual width = 6 ft
what is the actual area of the trampoline?

Explanation:

Step1: Understand the scale

The scale is \(1\) in. : \(3\) ft. This means to convert inches (scale drawing) to feet (actual), we multiply by \(3\).

Step2: Calculate the area

The formula for the area of a rectangle is \(A = l\times w\). We know the actual length \(l = 12\) ft and actual width \(w=6\) ft.
Substitute into the formula: \(A=12\times6\)

$$A = 72$$

Answer:

\(72\ \text{ft}^2\)
