Find the distance between points P(1,2) and Q(4,8) to the nearest tenth.

A. 5
B. 6.7
C. 11.2
D. 9

the answer will be option B 6.7

Step-by-step explanation: in co-ordinate geometry, let the P(x1, y1) and Q(x2, y2) be two points.

so their distance will be = sqaure root of ((x1 - x2)^2+(y1 - y2)^2)

here we take x1 = 1 , y1 = 2

and x2 = 4 , y2 = 8

so putting the values in the equation we get,

=

the answer is 489
