Yall! Do any of you have edge???

ignore my red line it means nothing

In vertex form:
w=(-6, 6)
u=(5, 0)
v=(-2, -1)
u+3v-w/2= (5,0)+(3*-2,3*-1)-(-6/2, 6/2) = (5+3*-2-(-6/2), 0+3*-1-6/2) = (5-6+3, 0-3-3)=(2,-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
