A scale drawing of a regular parking lot is shown. If the length (longer side) of the parking lot is actually 48 meters, what is the scale factor for the drawing?

(Answer must be written to the nearest hundredth below. )

_ meters

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
