Answer 2

Given :   Standing in row and column make a coordinate system.

100 students  assemble in prayer in 10 rows

To Find :distance between A and B

Solution:

A = ( 3 , 4)

B = ( 6 , 7)

C = (9 , 4)

D = ( 6  , 1)

distance between A and B

A = ( 3 , 4) B = ( 6 , 7)

= √(6 - 3)² + (7 - 4)²

= √3² + 3²

= √18

= 3√2

distance between A and B  is  3√2

distance between C and D

C(9,4) and D (6,1)

= √(6 - 9)² + (1 - 4)²

= √(-3)² + (-3)²

= √18

= 3√2
