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?
8 ft²
24 ft²
36 ft²
72 ft²

Explanation:

Step1: Find the scale factor for length and width

The scale is \(1\) inch \( = 3\) feet.

Step2: Calculate actual length

Given length in drawing \(l = 4\) inches. Actual length \(L=4\times3 = 12\) feet.

Step3: Calculate actual width

Given width in drawing \(w = 2\) inches. Actual width \(W=2\times3=6\) feet.

Step4: Calculate actual area

The formula for the area of a rectangle is \(A = L\times W\). Substitute \(L = 12\) and \(W = 6\). So \(A=12\times6=72\) square - feet.

Answer:

The number to multiply each length in the scale drawing by to find the actual length is \(3\). The actual length is \(12\) ft, the actual width is \(6\) ft. The actual area of the trampoline is \(72\) \(ft^{2}\).
