a pool needs to be 9 feet in length the the plans are 18 by 36 inches what is the scale factor of the dilation you must use to build the pool?
+23245 If the scale is 18" x 36" with the width represented by the 18" and the length represented by the 36",
these value can be changed into feet by dividing by 12: 18" = 1.5' and 36" = 3'.
If the real length is to be 9' while the scale is 3', the multiplying factor (the expansion factor) is 3.
(Because 9' ÷ 3' = 3.)
