+195 The diagonals of rhombus $MNOP$, have lengths of $12\ \text{mm}$ and $16\ \text{mm}$. What is the perimeter, in millimeters, of rhombus $MNOP$?
+57 The diagnols of a rhombus intercect at a right angle and bisect each other so each triangle has side lengths of 6, 8, and the hypotunuse. Using pythagorean each side is 10mm so the perimiter is 40mm.
