Question

Represent the value of $\sqrt{4.3}$ geometrically on number line.

Answer 1

Draw a line segment AB = 4.3 units and extend it to C such that BC = 1 unit.
Find the midpoint O of AC by drawing the perpendicular bisector of AC.
With O as centre and OA a radius, draw a semicircle.


Now, draw BD perpendicular to AC, intersecting the semicircle the semicircle at D. Then, $BD=\sqrt{4.3}$ units.
With B as centre and BD as radius, draw an arc, meeting AC produced at E.
Then, $BE=BD=\sqrt{4.3}$ units
