Question

darian wants to build a regulation-size pool table that is 9 feet in length. the plans he ordered are 18 by 36 inches. what is the scale factor of the dialation he must use to build the regulation pool table

Answer 1

normally, length>width

so if it is 9ft in width then

36>18
so
36inches:9ft
divide both sides b 9
4inches:1ft

so the scale factor is 4in:1ft
