Give the slope between the points
(-2,3) (-5, -9)

M = (-9 - 3) / (-5 - -2)
m = -12 / -3
m = 4

The slope is 4.

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
