Question

how to represent root 3.5 on number line geometrically tell with pic

Answer 1

take 3.5 unit
then again take 1 unit
then draw perpendicular bisector of A and C
then take o c as radis and draw semicircle
draw straight line joining B to circle
then take BE and stretch from b to no. line

Answer 2

The length of $OE$ also is $\sqrt{3.5}$

Step-by-step explanation:

Given,

Represent $\sqrt{3.5}$ on number line geometrically.

Following steps:

• Draw a number line as shown in figure.
• From point $O$, take $3.5$ point on left name as $A$ and take $1$ point on right name as $B$
• Bisect the line $AB$ to get mid point of the line name as $C$
• Take $C$ as a center and $AC$ as radius draw an semi circle.
• Using set-square draw perpendicular line through point $O$ which touch the circle line at $D$

• The length of $OD$ is $\sqrt{3.5}$

• $O$ as center and $OD$ as radius draw another semi circle which intersect the number line at $E$

Hence, The length of $OE$ also is $\sqrt{3.5}$
