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 = 16 ft actual width = 10 ft what is the actual area of the trampoline? 40 ft² 80 ft² 160 ft² 240 ft²

Explanation:

Step1: Identify scale factor

Given 1 in. = 2 ft, the scale - factor is 2.

Step2: Calculate actual length

The length in the scale - drawing is \(l = 8\) in. Actual length \(L=8\times2 = 16\) ft.

Step3: Calculate actual width

The width in the scale - drawing is \(w = 5\) in. Actual width \(W = 5\times2=10\) ft.

Step4: Calculate actual area

The area formula is \(A = L\times W\). Substitute \(L = 16\) ft and \(W = 10\) ft. So \(A=16\times10 = 160\) \(ft^{2}\).

Answer:

160 \(ft^{2}\)
