Question

Represent √7.2 on number line.​

Answer 1

Draw a line and mark AB = 7.2 units

From B mark another point C such that BC = 1 unit.

Locate the midpoint of AC and mark it as O.

With O as centre and radius OA or OC draw a semi-circle.

Draw perpendicular at point B.

Let the perpendicular intersect the semi circle at D.

Here BD represents √(7.2) Now with B as centre and radius BD draw an arc on the straight line.

Mark the intersection as X.

Then BX represents √(7.2)
