Hello, please help me out with this question.

In additional, the answer is not 45.364

The blade of a canoe paddle can be modeled as an ellipse (see below}, with the major axis of the blade (between points A and B] having length 19 inches, and the miner axis having length 8 inches. Blades are typically tapered, so that there is more material near the shaft (point A} than near the tip (point B]. Suppose that the tapering function is linear with the density at point A given by 0.1425 and the density at point B by c.04v5 ounces per sq. inoh. Determine the weight of the paddle's blade
