Introduction

In mathematics, the perimeter of a rectangle is a fundamental concept that is often used to calculate the total distance around the shape. Given a rectangle with length 'x' and width 'x + 3ax', we aim to determine the perimeter and explore the possibility of expressing it in the form 'x x + 3ax'. In this article, we will delve into the mathematical concepts and formulas required to solve this problem.

What is the Perimeter of a Rectangle?

The perimeter of a rectangle is the total distance around the shape, which can be calculated by adding the lengths of all its sides. For a rectangle with length 'l' and width 'w', the perimeter (P) can be calculated using the formula:

P = 2(l + w)

Calculating the Perimeter of the Given Rectangle

Given the length 'x' and width 'x + 3ax', we can substitute these values into the perimeter formula:

P = 2(x + (x + 3ax))

Simplifying the Expression

To simplify the expression, we can start by combining like terms:

P = 2(2x + 3ax)

Next, we can distribute the 2 to both terms inside the parentheses:

P = 4x + 6ax

Is it Possible to Express the Perimeter in the Form 'x x + 3ax'?

Now that we have simplified the expression for the perimeter, we can compare it to the given form 'x x + 3ax'. However, we notice that the simplified expression is not in the exact form 'x x + 3ax'. The reason for this discrepancy lies in the fact that the perimeter formula involves the sum of the length and width, whereas the given form implies a product of the length and width.

Conclusion

In conclusion, we have calculated the perimeter of the given rectangle using the formula P = 2(l + w) and simplified the expression to P = 4x + 6ax. While the simplified expression is not in the exact form 'x x + 3ax', it is still a valid representation of the perimeter. Therefore, it is not possible to express the perimeter in the exact form 'x x + 3ax'.

Additional Insights

The perimeter formula P = 2(l + w) is a fundamental concept in geometry and is used to calculate the total distance around a rectangle.
The simplified expression P = 4x + 6ax can be further manipulated using algebraic techniques to obtain different forms of the perimeter.
The discrepancy between the simplified expression and the given form 'x x + 3ax' highlights the importance of carefully interpreting mathematical expressions and formulas.
