1:100 mean:
1cm of a plan drawn represents 100 cm
100 cm = 1 m
1cm of a plan drawn represents 1m
1 cm x 1 cm = 1cm²
If 1cm of a plan drawn represents 1m then 1cm² of a plan drawn represents 1m²
30 cm² represents 30 m²
1cm of a plan drawn represents 100 cm
100 cm = 1 m
1cm of a plan drawn represents 1m
1 cm x 1 cm = 1cm²
If 1cm of a plan drawn represents 1m then 1cm² of a plan drawn represents 1m²
30 cm² represents 30 m²
