Best ResponseYou've already chosen the best response.0If we enlarge something "to scale" or "by a factor" or "using a scale factor" we simply multiply each side of the object by the same amount, by the factor. In this case the scale factor is 7.5 so multiply each side by 7.5 and we will get a new rectangle with longer sides. 6*7.5 = 45 8 * 7.5 = 60 dw:1437408705943:dw What is the area and perimeter of this larger, "scaled" rectangle?

Best ResponseYou've already chosen the best response.0Since it is "increased/enlarged " using "scale factor" We can, safely,do this: 6*7.5 and 8*7.5

Best ResponseYou've already chosen the best response.0Perimeter = 2(l + w)=2(45 + 60) = 2(105) = 210cm Area = lw = 45*60 = 2700cm^2
