The general rule for rotation of an object 90 degrees is (x, y) --------> (-y, x). You can use this rule to rotate a pre-image by taking the points of each vertex, translating them according to the rule, and drawing the image
Since a equals 2, 2 plus 27 is equal to 29. So your answer is 29. Hope that helped:)
