Step-by-step explanation:
s = side of square
l = length of rectangle = s + 3 cm
w = width of rectangle = s - 2 cm
s² + 30 = (s + 3)(s - 2) = s² + - 2s + 3s - 6 = s² + s - 6
30 = s - 6
s = 36 cm

Step-by-step explanation:
The 270° CCW rotation is described by the transformation ...
(x, y) ⇒ (y, -x)
That is, the first row of the transformed coordinate matrix is the same as the second row of the input matrix. The second row of the output matrix is the opposite of the first row of the input matrix.
