Question

Represent √8.5 on number line ​

Answer 1

Step-by-step explanation:

Draw a line segment of length 8.5 and name it as AB.

Add a line segment of 1cm to it.

It will be BC.

Now AC together will be 9.5cm.

Draw the perpendicular bisector of AC by taking the compass and cutting an arc from point A and point C.

Name the point of intersection of the arcs as P and the point where the bisector meets AC as Q.

Keeping compass at Q and taking radius = PQ draw a semicircle from A to C.

Now at point B make an angle of 90 degree or in other words it is a perpendicular.

Name the point where the perpendicular meets the semicircle as R.

Length of RB is the answer.
