Preston drew a blueprint of an additional room he is planning to add to his house. On the blueprint, 1 centimeter is equal to 4 feet in the actual room. If Preston wants the room to measure 12 feet by 16 feet, what are these dimensions on the blueprint?

A.
4 cm by 6 cm
B.
6 cm by 8 cm
C.
3 cm by 4 cm
D.
3 cm by 8 cm

To find the dimensions on the blueprint, we first need to convert the actual room dimensions to centimeters.

12 feet is equal to 12 x 4 = 48 centimeters on the blueprint.
16 feet is equal to 16 x 4 = 64 centimeters on the blueprint.

So, the dimensions on the blueprint are 48 cm by 64 cm.

Therefore, the answer is B. 6 cm by 8 cm.
