Answer:
16%
Step-by-step explanation:
The mean is 25, and the standard deviation is 1.
26 is 1 standard deviation above the mean.
According to the empirical rule, 68% of the population is between -1 and +1 standard deviations. That means that 32% is less than -1 or greater than +1 standard deviations. So half of that, or 16%, is greater than +1 standard deviations.
Plugging in the values, we get 7(6)-4=42-4=38.

Perimeter is the sum of the 4 walls:
11 + 11 + 9 + 9 = 40 feet
