The dimensions of a room on a 1:50 scale plan are 60 mm x 85 mm. Calculate the area of the room in m2.

Answer 1

On a 1:50 scale plan, 1 mm on the plan represents 50 mm in real life.

So, to find the actual dimensions of the room, we need to multiply the dimensions on the plan by 50:

Actual length = 60 mm * 50 = 3000 mm = 3 m
Actual width = 85 mm * 50 = 4250 mm = 4.25 m

Now we can calculate the area of the room:

Area = length * width
Area = 3 m * 4.25 m
Area = 12.75 m2

Therefore, the area of the room is 12.75 m2.
