Question

Represent square 9.3 on the number line ?​

Answer 1

Step-by-step explanation:

STEPS: 1: On a numberline mark AB = 9.3 unit & BC= 1 unit.

2: Mark O the mid point of AC

3: Draw a semicircle with O as centre & OA as radius

4: At B draw a perpendicular BD.

5: BD = √9.3 unit

6: Now, B as centre, BD as radius, draw an arc, meeting the numberline at E.

Now, with BD or BE = √9.3 as radius , with 0 ( origin) of the number line as centre, draw an arc on the the number line, intersecting at point ‘k’. And this point ‘k' lies between integers 3 & 4, & represents √9.3

JUSTIFICATION:

BD = √ {(10.3/2)² - (8.3/2)²}

=> BD = √{10.3²- 8.3²)/4 }

=> BD = √{(10.3+8.3)(10.3–8.3)/4}

=> BD = √{18.6*2/4}

=> BF = √{37.2/4}

=> BD = √9.3 = BE

Answer 2

Answer:

Hope it helps...

Step-by-step explanation:

1. Draw a line segment AB of length 9.3 units
2. Extend the line 1 unit more such that BC = 1 units
3. Find the midpoint of AC
4. Draw semicircle with center O and radius OC
5. Draw a line BD perpendicular to AB, intersecting the semicircle at point D
6. Here BD = √9.3 to represent it in number line draw a arc DE such that BE= BD
7. Here BE is our required line
