Question

Repregent under root 3.5on number line

Answer 1

steps of construction

1.draw line segment OX

2. take O as a centre and draw an arc of 3.5 cm on line segment OX name it 'A'

3.now take A as a centre draw an arc of 1 cm intersecting on line segment OX name it 'B'.

4. now draw the perpendicular bisector of OB.

4.where the bisector intersect on line segment OX name name it 'P'.

5.now take p as a centre and PO as a radius draw a semicircle

6.this semicircle will intersect at 'B'.

7.draw a perpendicular line from A to the semicircle name it 'S'.

8.take A as a centre and AS as a radius draw an arc so that it intersect on line segment OX name it 'R'

9. 'R'=√3.5
