Question

How to represent root 3.5 on number line

Answer 1

1 :draw a line and mark point A on it.
2:mark a point B on the line drawn in step 1 such that AB=3.5
3:mark a point C on AB produced such that BC=1unit.
4:find midpoint of AC . let the midpoint be O.
5:taking O as the center and OC=OA as radius draw a semi-circle. Also draw a line passing through B perpendicular to OB. suppose it cuts the semi circle at D.
6: taking B as the center and BD as radius draw an arc cutting OC produced at E. Point E so obtained represent root 3.5
