Question

Find the distance between the points:

A(9, 3) and B(15, 11)

Answer 1

A(9,3) and B(15,11)
The given points are A(9,3) and B(15,11)
`Then ( x_2= 9,y_1=3) and (x_2 = 15 , y_2=11)`

`AB=sqrt((x_2-x_1)^2 +(y_2-y_1)^2)`

`=sqrt((15-9)^2 +(11-3)^2)`

`=sqrt((6)^2+(8)^2)`

`=sqrt(36+64)`

`= sqrt(100)`

= 100 units
