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.
3 cm by 8 cm
B.
6 cm by 8 cm
C.
4 cm by 6 cm
D.
3 cm by 4 cm
A. 3 cm by 8 cm
To find the dimensions on the blueprint, we divide the actual dimensions by the scale factor of 4.
12 feet / 4 = 3 cm
16 feet / 4 = 4 cm
Therefore, the blueprint dimensions are 3 cm by 8 cm.
