The scale factor of rectangle jklm to rectangle qrst is . the perimeter of rectangle qrst is 12 units, and the perimeter of rectangle jklm is units. the area of rectangle qrst is units2, and the area of rectangle jklm is 128 units2. if proportional dimensional changes are made to a figure, then the perimeter will change by the scale factor, and the area will change by the scale factor.

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24

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.
