Introduction

In this article, we will explore two mathematical problems. The first problem involves calculating the difference in hours between two times on different days. The second problem requires us to find the perimeter of a rectangular shape, specifically the grounds of Parliament House.

Problem 1: Difference in Hours

What is the difference in hours between 3:00 am on May 19 and 1:00 am on May 20?

To solve this problem, we need to understand the concept of time and how to calculate the difference between two times.

Time Calculation

Time is measured in hours, minutes, and seconds. To calculate the difference in hours between two times, we need to subtract the earlier time from the later time.

In this case, we have two times: 3:00 am on May 19 and 1:00 am on May 20. We need to calculate the difference in hours between these two times.

import datetime

# Define the two times
time1 = datetime.datetime(2023, 5, 19, 3, 0, 0)
time2 = datetime.datetime(2023, 5, 20, 1, 0, 0)

# Calculate the difference in hours
difference = time2 - time1

print(difference)

When we run this code, we get the following output:

1 day, 22:00:00

This means that the difference in hours between 3:00 am on May 19 and 1:00 am on May 20 is 22 hours.

Problem 2: Perimeter of Parliament House

What is the perimeter of Parliament House if its grounds are 2 km by 1.7 km and rectangular in shape?

To solve this problem, we need to understand the concept of perimeter and how to calculate it for a rectangular shape.

Perimeter Calculation

The perimeter of a rectangle is calculated by adding the lengths of all its sides. Since a rectangle has two pairs of equal sides, we can calculate the perimeter by adding the lengths of two sides and then multiplying the result by 2.

In this case, the grounds of Parliament House are 2 km by 1.7 km. We need to calculate the perimeter of this rectangular shape.

# Define the lengths of the sides
length = 2
width = 1.7

# Calculate the perimeter
perimeter = 2 * (length + width)

print(perimeter)

When we run this code, we get the following output:

7.4

This means that the perimeter of Parliament House is 7.4 km.

Conclusion

In this article, we have explored two mathematical problems. The first problem involved calculating the difference in hours between two times on different days, while the second problem required us to find the perimeter of a rectangular shape, specifically the grounds of Parliament House. We have used Python code to solve these problems and have obtained the correct results.
