Well, honey, to find the perimeter of a rectangle, you add up all the sides. So, for your rectangle with sides of 12m and 8m, you simply add 12 + 12 + 8 + 8 to get a perimeter of 40 meters. Voila!

Assuming that the measures given in the question refer to the lengths of the sides of the rectangle, the answer is 40 metres.
