Question

The distance between (0, 0) and (0, 1) on a certain coordinate plane is 1cm. The distance between (0, 0) and (1, 0) on that same coordinate plane is 1cm. What is the distance between (0, 0) and (1, 1)? Explain your answer.

Answer 1

=distance betwen 2 points

d=sqroot[(x2-x1)^2+(y2-y1)^2]

In this case x1=0 y1=0 x2=1 y2=1

d=sqroot[(1-0)^2+(1-0)^2]

d=sqroot(1^2+1^2)

d=sqroot(1+1)

d=sqroot(2)

d=1.41421 cm
