Question

If A(7,5) and B(2,5) then find D(A,B)

Answer 1

Answer:

5.

Step-by-step explanation:

A = ( 7 , 5 )

x1 = 7 , y1 = 5 ;

B = ( 2 , 5 )

x2 = 2 , y2 = 5 ;

D(AB) =

$\sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} }$

D(AB) =

$\sqrt{ {(2 - 7)}^{2} + {(5 - 5)}^{2} }$

D(AB) =

$\sqrt{ {( - 5) }^{2} + 0 }$

D(AB) =

$\sqrt{25}$

D(AB) = 5.

Distance between points AB is 5 .
