Tom bought 6 new baseball trading cards to add to his collection. The next day his dog ate half of his collection. There are now only 44 cards left.
How many cards did Tom start with?

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
