Question

A scale drawing of a door is 2 cm high. If the scale is 1 cm = 4 meters, what is the actual height of the door?

Answer 1

It should be 4 meter high.

Answer 2

Answer: 8 meters.

Step-by-step explanation: if in a scale drawing a door is 2 cm high, and the scale is 1cm=4meters, then 2cm will be the double:

1cm=4 meters

2cm=2*(4 meters)

2cm=8 meters.

So the actual height of the door is 8 meters.
