Answer:
We know that the total area under the normal curve is 100%. According to the empirical rule of Normal distribution:
Approximately, 68% of data lies within 
standard deviations of mean.
Approximately, 95% of data lies within 
standard deviations of mean.
Approximately, 99.7% of data lies with 
standard deviations of mean,
Therefore, in a normal curve, roughly 95% of all cases fall within plus or minus two standard deviations.
Answer:
- Perimeter: 7.8
- Area: 3.1
Step-by-step explanation:
- Perimeter = all sides added up together
- 2.8 + 2.8 + 1.1 + 1.1 = 7.8
- Area = L × W
- 2.8 × 1.1 = 3.08
- Round 3.08 to the nearest tenth: 3.08 → 3.1
