6x-5y=2
-x+2y=9
given the system of equations above, what is the value of y

The answer is y=6
if you multiply the bottom equation by 6 combine them and solve for y

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
