Find the average of the x-intercepts. x=2 x=-4

Step 1: Subtract 2x from both sides.

x−2x=2x−4−2x

−x=−4

Step 2: Divide both sides by -1.

−x−1=−4−1

x=4

x=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
