Question

plz help me out

Answer 1

The line segment 7 cm long is shown below.

Explanation:

First we draw a line line segment whose length is 7 cm long. Then we divide the line in small parts.

The length of each part is 1 cm.

Six points on the line segment divides the line in 7 equal parts and length of each part is 1 cm.

From the figure it is noticed that we have total 7 small parts and length of each part is 1 cm. So length of 7 parts is

`7* 1=7`

Hence the total length of line is 7 cm.
