Question

Darren wants to build a regulation size pool table that is 9 feet in length. The plans he ordered are 18 x 36”. What is the scale factor of the dilation he must used to build a regulation size table

Answer 1

Answer:

Width and length of the plan is 18 inches and 36 inches. The required length of the table is 9 feet, which is 9 * 12 = 108 inches

So scale factor = $\frac{Required length of the table}{Length of the plan}$ = $\frac{108}{36}$ = 3

The answer is 3
