How to solve this problem?
-3 d +7 > 25

Subtract 7 from both sides so you're left with -3d>18 and then divide by -3 on both sides and remember to flip the sign bc you're dividing by a negative so d<-6

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
