A scale drawing of a game room is shown below: A rectangle is shown. The length of the rectangle is labeled 2 inches. The width of the rectangle is labeled 4.5 inches. The scale is 1 to 30. What is the area of the actual game room in square feet? Round your answer to the nearest whole number. 9 ft2 23 ft2 56 ft2 270 ft2

there are two strategies. One way: multiply both sides by 30 to get the size of the big figure. then figure out its area. 2nd way: find the area of the small figure. then multiply by 30^2 (because we know area will go up by a factor of 30*30)
the other problem is that your answer will be in square inches. to change to square feet you need to divide square inches by (12*12) to get square feet.
so the first one we get 135 and 60 tnow how do we find the area
@phi
ok, but remember that those are in inches. can you change those to feet ? (divide by 12)
then we multiply those and get 8100 then we divide by 144 we get 56.25
but then if we divide 135 by 12 we get 11 .25 andthen we divide 60 / 5 then we get 5 so we multiply those and get 56.2 anyway
56.25* sorry
yes, or if we first changed them to feet 135/12 * 60/12 (which by the way is \( \frac{135\cdot 60}{12\cdot 12} \) ) we would get 11.25*5= 56.25 round to 56
ok so 56 ft^2
yes, it's good (when learning) to see how to do it different ways. It might sink in !
ok well thanks for the help today
@iceicebaby you do flvs don't you.
