Best ResponseYou've already chosen the best response.0it might be useful to know that any linear scale translates into a squared scale when it comes to area for example: a 2x2 square has linear sides of 2, and an area of 4 if we scale it by 3; the sides become 3(2), and the area is therefore 3(2)*3(2), or just 3^2 (4)

Best ResponseYou've already chosen the best response.015k = 4, when k=4/15, so our linear scale is 4/15 to work with in this case

Best ResponseYou've already chosen the best response.0lets spose we wanted to work the ratio of the example on squares ... 6k = 2, when k=2/6 = 1/3 k^2 = 1/9  now the areas of our square example is 36 and 4: 4/36 = 1/9 .... so what can we conject from this?

Best ResponseYou've already chosen the best response.0lets see if the shape matters the area of the larger is 15h/2 for whatever the height is the area of the smaller is 15(4/15) * h(4/15)/2 \[\frac{15h(4/15)^2/~2}{15h/2}\] \[\frac{15h(4/15)^2}{15h}\] \[\frac{h(4/15)^2}{h}\] \[\frac{(4/15)^2}{1}\] doesnt seem to matter what shape it is, as long as they are similar shapes :)
