Question

find √4.2 geometrically​

Answer 1

given value is 4.2

1. Draw a line l

2. now on line l draw line segment

of measure 4.2+1=5.2

3. name the line segment as AB

4. draw a perpendicular from point AB. the point at which the perpendicular line bisect the line l, name that point C and draw a semi circle from C joining the points AB.

5. now from the point of line segment measure 4.2 draw a line of 90° intersecting the semi circle.

6. take radius= distance between the point of 4.2 and the intersecting point on semi circle.

7. taking this radius cut line l from point of line segment 4.2

The point at which the arc cut the line l, name the point as D. the line from A to D is √4.2
