Question

represent root under 3.2 on a number line​

Answer 1

Make 3.2 a fraction I.e. 32/10 and represent it as 30/10,31/10,32/10,33/10 and so on

draw line of cm. 3.2 and name AB increase 1 cm. from point B and make C take compass and draw semicircle from point A to C with B as centre and BD as radius , draw an arc ,meeting ac prodoced E then ,BE = BD = root 3.2

root 3.2

Answer 2

Answer:

Step-by-step explanation:

Draw a line AG =5 cm.  Mark B, C, D and E as shown.

BF = 3.2 cm.  Draw perpendicular Bisector of HG at F.

Similarly draw perpendicular bisector of AC at B.

Now do the construction for angular bisector of the right angle at B and F.

The two angular bisectors intersect at I.  BI = FI = √3.2  cm.  as BF = 3.2cm

Draw an arc from B with radius BI onto  AG.

SO  BJ  =  √3.2 cm
