Introduction

In mathematics, the area of a rectangle is a fundamental concept that is used to calculate the space inside the rectangle. Given the side lengths of a rectangle, we can find the area by multiplying the length and width. In this article, we will explore how to find the expression in standard form that represents the area of a rectangle with side lengths of ${$ (x+6)$}$ and ${$ (2x+3)$}$.

Understanding the Problem

To find the area of the rectangle, we need to multiply the length and width. The length is given as ${$ (x+6)$}$ and the width is given as ${$ (2x+3)$}$. We can represent the area of the rectangle as the product of these two expressions.

Finding the Expression in Standard Form

To find the expression in standard form, we need to multiply the two expressions together. We can use the distributive property to multiply the expressions.

${$ (x+6)$ * [ $(2x+3)\$ = \[$ (x * 2x) + (x * 3) + (6 * 2x) + (6 * 3)$

Using the distributive property, we can simplify the expression as follows:

[$(2x^2 + 3x + 12x + 18)$

Combining like terms, we get:

[$(2x^2 + 15x + 18)$

Simplifying the Expression

The expression [$(2x^2 + 15x + 18)$ is the standard form of the area of the rectangle. This expression represents the area of the rectangle in terms of the variable x.

Conclusion

In this article, we have found the expression in standard form that represents the area of a rectangle with side lengths of [ $(x+6)\$}$ and ${$ (2x+3)$}$. The expression is ${$ (2x^2 + 15x + 18)$ and it represents the area of the rectangle in terms of the variable x.

Introduction

In our previous article, we explored how to find the expression in standard form that represents the area of a rectangle with side lengths of ${$ (x+6)$}$ and ${$ (2x+3)$}$. In this article, we will answer some frequently asked questions related to finding the area of a rectangle.

Q&A

Q: What is the formula for finding the area of a rectangle?

A: The formula for finding the area of a rectangle is length x width.

Q: How do I find the area of a rectangle with side lengths of ${$ (x+6)$}$ and ${$ (2x+3)$}$?

A: To find the area of a rectangle with side lengths of ${$ (x+6)$}$ and ${$ (2x+3)$}$, you need to multiply the length and width together. The expression in standard form that represents the area of the rectangle is ${$ (2x^2 + 15x + 18)$.

Q: What is the difference between the area of a rectangle and the perimeter of a rectangle?

A: The area of a rectangle is the space inside the rectangle, while the perimeter of a rectangle is the distance around the rectangle.

Q: How do I find the perimeter of a rectangle with side lengths of [ $(x+6)\$}$ and ${$ (2x+3)$}$?

A: To find the perimeter of a rectangle with side lengths of ${$ (x+6)$}$ and ${$ (2x+3)$} $, you need to add up the lengths of all four sides. The perimeter of the rectangle is 2(length + width) = 2($ { $(x+6)\$ + \[$ (2x+3)$) = 2($3x + 9$).

Q: What is the relationship between the area and the perimeter of a rectangle?

A: The area and the perimeter of a rectangle are related in that the area is equal to the product of the length and width, while the perimeter is equal to the sum of the lengths of all four sides.

Q: How do I use the area and perimeter of a rectangle to solve real-world problems?

A: The area and perimeter of a rectangle can be used to solve real-world problems such as calculating the cost of materials needed to build a room or a building, finding the area of a piece of land, or calculating the area of a rectangle-shaped object.
