Best ResponseYou've already chosen the best response.0Lol, well they tell us the scale is 1:20 right? So any idea what that means

Best ResponseYou've already chosen the best response.0If its 1:20 then you do 4 x 5 which equals 20

Best ResponseYou've already chosen the best response.0Ok well the 4 x 5 = 20 is the area, so we have 20 inches^2 now we are given that the scale is 1:20, which tells us the figure is only 1/20 size of the original. So it's probably easier if you do \[4 \times 20\] and \[5 \times 20 \] first then convert it to inches.

Best ResponseYou've already chosen the best response.0convert it to feet* OR you can find area then convert to square feet, doesn't matter

Best ResponseYou've already chosen the best response.0ok can you do the work in steps so that i understand it better?

Best ResponseYou've already chosen the best response.0Well I mean we are given that the dimensions are 4 by 5 inches, and the proportion is 1/20, we want its original size but in square feet, so notice there's two things to this problem. So we can start off by multiplying 4 and 5 by 20 to get the original scale right? \[4 \times 20 = 80~~~~\text{and}~~~5 \times 20 = 100 \] but note these dimensions are still in inches, you can now convert it to feet then find the area which is just \[A = lw\] or you can find area first and convert it to square feet. I think I'll leave the rest to you.

Best ResponseYou've already chosen the best response.0I think there is enough information here already, you should try to figure it out on your own now :), good luck.
