what are the coordinates of the vertices of triangle a’b’c’ after a reflection across a line through point p with a y-intercept at y=-2, followed by a translation t< 3,3> ?

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
