Question

Using scale factor of 1 inch = 5 feet, the blueprint dimensions of bedroom that is 12 feet x 18?

Choices
A) 2.2 in. X 3.3 in.
B) 2.4 in. X 3.6 in.
C) 2.8 in. X 4.2 in.
D) 2.9 in. X 5.0 in.

Answer 1

The only thing that you need to do on this problem is divide.

The first dimension is 12 feet so we need to divide that by 5.

12 / 5 = 2.4

The first dimension is 2.4.

From this point we don't need to solve any more because there is only one answer with 2.4 in it, so we can conclude that the answer is B
