Question

Find the distance of AB.

Answer 1

3

Explanation:

A ( 2, 2 )

( x1, y1 ) = ( 2, 2 )

Here,

x1 = y1 = 2

B ( - 2, - 2 )

( x2, y2 ) = ( - 2, - 2 )

Here,

x2 = y2 = - 2

Distance formula : -

d = √ ( x2 - x1 )² + ( y2 - y1 )²

AB = √ ( - 2 - 2 )² + ( - 2 - 2 )²

= √ ( - 2 )² + ( - 2 )²

= √ 4 + 4

AB = √8

The value of √8 is 2.828.

Roundoff to nearest 10 is 3.
