Scale-drawing

This table in 2 m long and 1 m wide. A life-size plan would not fit on a page so it must be drawn to scale so that the shape stays correct and so that anyone looking at the plan can easily find true sizes. each meter of the table can be shown by 1 cm on the plan. check that the plan incorrect. the scale can be given in 4 ways:

  1. 1 cm represents 1 m i.e. 1 cm = 1 m
  2. as a ratio 1:100
    (1 cm on the map is 1 m = 100 cm of real object.)
  3. as a fraction, 1 the map in 100 times smaller than the table.
    100
    (1:100 in a very large scale, suitable for plans of rooms.)
  4. with a line 0 to 1 m

Scale in the ratio between the distance on the map and the distance on the real ground. It shows how many times the map has been reduced from the real size of the area it represents.

Maps with different scales


Measuring distances

To find the shortest distance between two places or along a straight road, measure carefully with a ruler, then change the cms to the real measurement

For example, the distance between the zoo and Pulchowk stupa in 1.3 cm and the scale in 1:50,000
1.3 * 50,000 = 65,000
so the real distance in 65,000 cm = 650 m

Make your own accurate plans

1. Measure your bench or desk in cms.

You will do a plan with scale 1:50 (1 cm= M½ m)
Give it a title and write the scale.
Divide the real length (in cms) by 50 = This gives you the length to draw your plan.

2. Now do a plan of your classroom with scale 1:100 or 1 cm= 1m. Can you mark the exact spot where you sit?

3. Do a plan of the ground floor of your house, showing the different rooms. Use a scale of 1:100. A piece of string in useful for measuring. Give your plan a title, show the scale and label the rooms. You could colour it, making the lines show up strongly in a back.



  • 1 cm represents 1 m i.e. 1 cm = 1 m
  • 65,000 cm = 650m
  • Scale in the ratio between the distance in the map and the distance in real ground. 
  • To find the shortest distance between two places or along a straight road, measure carefully with a ruler, then change the cms to the real measurement.

Very Short Questions

The area of my house is:

Length of my house (l) = 20m

Width of my house (b) = 5m

The area of my house (A) = ?

A= l x b= 20 x 5 = 100m2.

Therefore, the area of my house is 100m2.

Map is the representation of whole or some parts on the earth or any other parts, or objects found in any body of universe on a flat sheet of paper with appropriate scale and color (so that each of the point in the map can show the real difference in location of any objects).

There is no field of study where there is no use for map. Map expresses a lot of spatial information through graphics that is easy to extract and understand. It’s relationship in combination with social attributes. Moreover, it helps to understand the problems and prospects of an area in terms of resources, infrastructures, etc. maps present multiple layers of information simultaneously; so we can compare different variables quickly. That is why it is said that picture is worth thousand words.
