Question 972426
The shortest side of the original polygon is 6


"the shortest side is reduced by 2 inches" so 6 turns into 6-2 = 4


Divide 4 by 6 to get 4/6 = 2/3. So this means that we must multiply every dimension by 2/3 to get a smaller similar polygon. So for example, the side 10 turns into 10*2/3 = 20/3 = 6 & 2/3. The same applies for the other dimensions.
