The perimeter of a rectangle is given by the formula 2*(length + width).

First, we need to find the length and the width of the rectangle. The length is the distance between points L and M, which is |-5 - (-2)| = 3 units. The width is the distance between points M and N, which is |-6 - (-1)| = 5 units.

Now, we can calculate the perimeter: 2*(3 + 5) = 2*8 = 16 units.

Therefore, the perimeter of rectangle LMNO is 16 units.

Answer: 16 units
