Astore is having a clearance sale where merchandise on the sales rack is reduced by 80% from the original price. if a jacket was originally priced at $76, what is the sale price.

76 - 80% = 15.2 
$15.20 is your answer :)

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
