Construct a graphical scale to show kilometers and meters for the given R.F. 1:50,000.
Answers
Explanation:
According to a standard, generally, a length of 15 cm is taken to draw a graphical scale. 1:50,000 means that 1 cm on map shows 50,000 cm on ground. In other words, 1 cm shows 50,000 cm.
15 cm shows 50,000 x 15/1,00,000
15 cm = 7.5 km
Since 7.5 km is not an integer, so we can round it off to 5 or 10. Let us round it off to 5 km in this question.
Therefore, we need to make the following calculations to express the scale on a length of 5 km.
7.5 km is shown by 15 cm line.
Therefore, for 5 km we can express it as 15 x 5/7.5
0. 5 km will be shown by 1 cm on line.
We can make the graph by following steps:
First of all draw a 10 cm line and divide it in 5 important parts. Except for one part from the left, let us give all parts a distance of one km. Now divide the first part in 10 equal parts and each part will be equal to 100 metres. We can divide it in five parts as well and taking one part as 200 metre and so on.
