003 (part 1 of 2) 10.0 points A carpenter's square of uniform density has the shape of an L, as shown in the figure. Assume: A (x, y) coordinate frame with the origin at the lower left corner of the car- penter's square. The x-axis is horizontal and to the right. The y-axis is vertically upward. Given: In the figure, B = 14 cm, C = 3.5 cm, D = 4.1 cm, E= 18 cm. Because the square is uniform...
