What is a line scale
Scale as a diagram called a line
What does this scale represent and calculate the distance in real life if the distance measured is 3cm on the map
In words, every centimetre on the map represent 3000cm or 30 m in real life
3x 30=90m in real life
1: 42 000 000 where 1cm = 420km. Calculate what is the distance if distance measured on map is 2cm
2 x 420 = 840 km in real life
