How do this maths question?
Please leave working out if you know the answer, thanks :)

Capt. Matticus is right in calculating the size of the grid. The side of one box is 4 mm wide.
However, he apparently misread the question. You're asked to work out the distance between M and J, not M and K.
Which makes the problem a lot easier, of course! :-)
The line of symmetry goes through points K and L as you probably realize. So, point M is on the same horizontal line than point J, just below the letter "p" of "five points".
Since J is 3 boxes to the left from the line of symmetry, point M will therefore be 3 boxes to the right.
In total, the distance between J and M is 6 boxes, equivalent to 24 mm.

First, figure out the size of a grid. There are 7 boxes between k and l and we're told that they're 28 mm apart.
28 mm / 7 boxes = 4 mm/boxes
If you drew a line between k and l, you'd hopefully see how there's a corresponding point for j that is missing. So, just find the distance from j to k and that'll be the distance from k to m.
j and k are separated by 2 vertical spaces and 3 horizontal spaces
4 * sqrt(2^2 + 3^2) =>
4 * sqrt(4 + 9) =>
4 * sqrt(13) =>
or 4 * 13^(1/2) mm.
See which one works.
