Answer:
m = 8
k = 7
Step-by-step explanation:
Remark
Unless this really is a parallelogram, it is not (easily) solvable. I think you likely intend it to be a parallelogram, so it has an easy solution. The diagonals bisect each other.
So m = 8 because the intersect point of the diagonal and the second one makes the two parts equal.
k + 4 = 11 Subtract 4 from both sides.
-4 -4
k = 7
