Answer:
A = 160 mm²
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = bh ( b is the base and h the height )
Given P = 52 and P = 2(b + h) , then
2(b + h) = 52 ( divide both sides by 2 )
b + h = 26 ( substitute b = 16 )
16 + h = 26 ( subtract 16 from both sides )
h = 10
Then
A = 16 × 10 = 160 mm²

Step-by-step explanation:
To find the mean of something you are finding the average, so add all the times they were late to school. Then divide by the number of numbers you had to add. You will have your answer by doing that. What it means to interpret your answer is to explain it.
1. multiply the number of absences by the number of students.
2. Add the number of absences
3. divide by the number of students.
1/ (15/6) ^2 = 1/225/4 = 4/225
