To find the area<span> of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the </span>area<span>.
Mean=0.48 standard deviation=0.01 thus using the z-score: P(x>0.5) we shall have the following: z=(0.5-0.48)/0.01=2 thus P(x>0.5) =1-P(x<0.5) =1-P(z<2) =1-0.9772 =0.0228
