Question

Represent square root of $7$ and $9$ by constructing a square root spiral.

Answer 1

The steps are as follows:

Mark a center point O

From point O, draw a horizontal line OA of scale 1 cm

From point A, draw a perpendicular line AB of scale 1 cm

Continue the same above 2 steps for BA of scale 1 cm

Join OA, representing $\sqrt{7}$

And, join OC, representing $\sqrt{9}$
