Your question doesn't really make sense.

2yrs would be my guess - but your'e missing quite a lot of information.

Well, feel of a ruler. A mm is lovely darn small. So .5mm could be an ant's finger, 5mm could be a bumble bee's finger, 50 mm is lovely virtually typical, and 500mm is the Jolly Green Giant's finger. A rectangular is identical facets. Area is LxW. What X what's 36? How approximately 6 x 6? so if the edges are 6 each and every, and perimeter is the whole going across the rectangular, then it could be 6 + 6 + 6 + 6, correct???? So 24 cm I wish I now not simply gave the solutions however helped you feel approximately the query too.
