The distance between r and t on the coordinate grid is units. (input whole numbers only.)

Could you give me the coordinates of R & T? Or give me a picture of the graph itself? either one should be enough to help you.

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
