liam is setting up folding chairs for a meeting. if he arranges the chairs in 8 rows of the same length, he has 5 chairs left over. if he arranges the chairs in 6 rows of that same length, he has 13 left over. how many chairs does liam have?

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
