The dimensions of the figure shown below are AB = 12.0 cm, BC = 6.9 cm, CD = 8.8 cm, AF = 9.3 cm and DE = 0.5*9.3 cm. The radius of the circle is r = 1.0 cm with the centre at (2,2). Step 1: Determine X, being the x-coordinate of the centroid of the shaded area and determine Y, being the y-coordinate of the shaded area. Note that X and Y are measured with respect to point A, using a conventional horizontal-vertical coordinate system. Step 2: Use the coordinates X and Y to solve the following equation to find Z: 12X+7Y=Z Write your final answer for Z (in centimetres) in the answer box below. Round your answer to the nearest centimetre. LL F E A B + C D
