1) draw a line AB of 5.6 cm.then draw a line B to C of 1 cm.

2)find the mid point of A and C through perpendicular bisector.name it as O.

3)with O as center and OC or OA ar radius draw a semicircle such that its one end is on A and other on C.

4)draw 90 degree on B such that it intersect the number line. Name the intersecting point D.

BD represents route 5.6.

5) with B as center and BD as radius draw an arc intersecting the number line.name it as F.

6)F represents route 5.6 on the number line.
