Consider a random point in the square (-1,1]x(-1,1], we want to estimate the average distance from the point to the origin. To do this, you may generate some points, and compute their distances to the origin, and then take average. To make your answer convincing, you should choose enough number of points such that the answer is stable for at least two decimal digits. "Norm' function might be helpful here.
