use the distance formula..., The distance of two points $(x _{1},y _{1}) and (x _{2},y _{2})$ is $d=\sqrt{\left( x _{2}-x _{1} \right)^{2}+\left( y _{2}-y _{1} \right)^{2}}$ now.., can you identify what is your $x_{1}, y_{1},x_{2},y_{2}$ ? :)

ok what is the distance formula between a and b . when A is (4,2) and b is (9,5) ?

3. anonymous

the general formula to find the distance between two points is the one that I write above..., now.., you can apply it in your case, just change the variable with the numbers...

i got 34 , is 2 squared 14 the answer?

5. hba

Underroot{34)

6. anonymous

$\sqrt{34}$ it cannot be simplified any more...

what about (2,12) and (7,2) ? what is the distance formula of those?

8. AravindG

why are you not able to do that?

your whole answer is 9 but the square root of 9 is three
