Construct a square root spiral

°TO CONSTRUCT A SQUARE ROOT SPIRAL
PROCEDURE
1. GET A TRACING PAPER AND MARK MN = 1 unit.
2. FOLD THE TRACING PAPER TO GET POINT N1 SUCH THAT MN PERPENDICULAR N N1 = 1 UNIT.
MN1 = under root 1²+ 1² = under root 2 units.
3. FOLD TO OBTAIN THE CREASE MN1 AND AGAIN FOLD THE PAPER TO OBTAIN THE POINT N2 IN SUCH A WAY THAT MN1 PERPENDICULAR TO N1 N2 AND N1 N2 = 1 UNIT.
MN2 = under root ( under root 2)² + (under root 1)² = under root 3 units.
4. REPEAT THE PROCESS TO GET THE POINTS N3 N4 N5 _______ TO OBTAIN THE LENGTH under root 4, under root 5, under root 6.........
5. HENCE, WE GET A SQUARE ROOT SPIRAL.
HOPE IT HELPS YOU
Answer:
Width of picture = 60cm
Length of picture = 1.8m=180cm
Perimeter of the picture ⟹2×(length+breadth)
⟹2×(180+60)cm=2×240cm=480cm
Ratio=Perimeter of picturewidth of picture=48060=81=1:8
