Question

10 centimeter represents 1 meter. If a class room is 5 centimeters by 7 centimeters. What are the actual dimensions of the classroom?

Answer 1

Answer:

The actual dimensions of the classroom are 50 cm x 70 cm

Explanation:

Scaling

When we need to represent real-world dimensions into small spaces, we use scaling. Distance scaling tells us what is the equivalence between the real units and the scaled units. In this case, we are told that 10 cm is equivalent to 1 meter. As 1 meter is 100 cm, it means that the scale is 100/10=10. Thus, each centimeter in the paper is equivalent to 10 cm in the real distance.

The classroom is 5 cm x 7 centimeters. Scaling back to the real values, the classroom has measures of 50 cm x 70 cm.
