Your answer is wrong 

Classroom activity concept in the square root is parallel take a large sheet of paper construct the square root spiral in the following session start with the point zero and role line segment op 1 of unit length draw a line segment P1 P2 perpendicular op1 of unit length sea figure point 19 now draw a line segment p2p 3 perpendicular to o p 2 then draw a line segment P3 P4 perpendicular to O3 continuing in this manner you can get the line segment p and minus one pi by drawing a line segment of unit perpendicular to o p in this manner you will have to create the app on Speed 2 P3 PN and join them to create a beautiful ispector ro
ot 3 root 3 root 4
