Question

Quadrilateral ABCD in the figure below represents a scaled-down model of a walkway around a historic site. Quadrilateral EFGH represents the actual walkway. ABCD is similar to EFGH.
What is the total length, in feet, of the actual walkway?

Answer 1

Figure?

Answer 2

The scaling used is such that 60 ft of actual walkaway is equivalent to 4 in of scaled down walkaway.

The total walkaway of scaled down version is 3 + 4 + 2 + 2 = 11 in.

Now to convert it to actual walkaway we have to first convert it into feet and then multiply by the scaling factor.

11 in = 11 * .0833 = 0.9167 ft

Now the actual walkaway if 0.9167/4*60 = 13.74 ft

Answer 3

Sorry one thing is wrong here.

The last step should be:

Now the actual walkaway if 0.9167/0.3333*60 = 165.02 ft
