Step-by-step explanation:
Given
Your measurement

Another students'

Solving (a): The area
Area is calculated as:

For you


For the other student


Solving (b): Reason for the variation in the areas
The given measurements are estimates of the dimensions of the rectangle.

Answer: 2.592 x 10^6 seconds
Explanation:
There are 3600s in 1 hr
And 24hrs in 1 day which mean
There are 3600 x 24 = 86400s in 1 day
And one month = 30 days
86400 x 30 = 2, 592, 000s in 1 month
Write in scientific notation:
2, 592, 000 = 2.592 x 10^6
