Perimeter of a rectangle is given by (2 × Length(l)) + (2 × Width(w)) = 2l + 2w
l= 11 feet
2(11) + 2w = 46
2w = 46 - 22 = 24
w = 24/2 = 12 feet
Width = 12 feet.

Answer:
B. 68%.
Step-by-step explanation:
We have been given that driving times for students' commute to school is normally distributed, with a mean time of 14 minutes and a standard deviation of 3 minutes.
First of all, we will find z-score of 11 and 17 using z-score formula.







We know that z-score tells us a data point is how many standard deviations above or below mean.
Our z-score -1 and 1 represent that 11 and 17 lie within one standard deviation of the mean.
By empirical rule 68% data lies with in one standard deviation of the mean, therefore, option B is the correct choice.
