Best ResponseYou've already chosen the best response.1Perimeter is the distance around the 2d shape, so dw:1433638990215:dw add all the numbers for the perimeter and the area of a rectangle is just length x width\[Area = l \times w\] once you have that you can multiply both of them by 7.5.

Best ResponseYou've already chosen the best response.1But you must multiply it by 7.5 for the scale factor

Best ResponseYou've already chosen the best response.1No that's the perimeter, the area of a rectangle is length multiplied by the width.

Best ResponseYou've already chosen the best response.0and whats the length and width

Best ResponseYou've already chosen the best response.1You should really know this by now, dw:1433640168475:dw Note that the scale factor for area, the change in area is equal to the scale factor squared, which means the scale factor for area is \[7.5^2\]

Best ResponseYou've already chosen the best response.1That's for the unscaled rectangle, yes.

Best ResponseYou've already chosen the best response.0so thats the length x width

Best ResponseYou've already chosen the best response.1How did you get the area?

Best ResponseYou've already chosen the best response.0area = 6 x 8 6 x 7.5= 45 8 x 7.5= 60 is that right? @Astrophysics

Best ResponseYou've already chosen the best response.1Not quite, nice try though. Remember what I said to note earlier: `Note that the scale factor for area, the change in area is equal to the scale factor squared, which means the scale factor for area is`\[7.5^2\]

Best ResponseYou've already chosen the best response.1\[area = l \times w \times 7.5^2\]
