Talk about it

What does the scale 1:2000 mean?

Scale: 1:2000

Distance on the map: actual distance = scale

Distance on the map/actual distance = scale

On the floor plan of a primary school with a scale of 1:2000, the length of the campus is 10 cm and the width is 6 cm. Find the actual length and width of the campus.

Length as shown: 10 cm

Actual length: 2000 × 10 = 20000 (cm) = 200 (m)

Width as pictured: 6 cm

Actual length: 2000×6=12000 (cm)=120 (m)

Answer: The actual length and width of the campus are 200 meters and 120 meters respectively.

Can the actual floor space of the school be calculated based on the scale?

On the floor plan of a primary school with a scale of 1:2000, the length of the campus is 10 cm and the width is 6 cm. Find the actual area of ​​the school.
