The actual area of the room is 30m2.
How do you calculate the area?
A square or rectangle's area can be computed by dividing its height by its width. If the height and width are in centimeters, the area is shown in cm2. If the height and width are in meters, the area is shown in square meters (m2).
There are 100 cm in a meter, so each centimeter on a design at a scale of 1:100 corresponds to one meter. In the example, a square centimeter actually equals a square meter. The scale drawing depicts a 30cm2 area, although the space is actually 30m2.
