Tia and her 5 friends are going to the ice skating ring. each person pays $5 for admission and $5 for food. write a numerical expression to find the total cost for admission and food.

The expression would be (5*6)+(5*6)=x
or you could shorten it and do (10*6)=x

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
