Question

Represent √4.5 on the number line.​

Answer 1

CONSTRUCTION

1.) Draw a line number line

2.) Draw a line OA of length 0.5cm on number line

3.) Again, draw a perpendicular line AB of length 0.5cm. Now you get a hypotenuse of length =√0.5 cm

4.) Now draw a perpendicular line BC to base OB of length 2cm. And join OC to make hypotenuse of length =√4.5

5.) Take compass , put the tip of compass on point O and the pencil on point C. And make a arc to numbers line.

7.) Arc cut the number line at point D =√4.5 cm
