Question

✓7.2 on number line diagram with explanation​

Answer 1

Step-by-step explanation:

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)
