Introduction

In mathematics, the study of geometric shapes and their properties is a fundamental aspect of understanding the world around us. Rectangles, in particular, are a type of quadrilateral with four right angles and opposite sides of equal length. In this article, we will delve into the dimensions of a rectangle and explore how to calculate its perimeter using mathematical formulas.

The Dimensions of the Rectangle

The dimensions of the rectangle are given as $\sqrt{50 a^3 b^2}$ and $\sqrt{200 a^3}$ . These values represent the length and width of the rectangle, respectively. To understand the significance of these values, let's break them down further.

The length of the rectangle is $\sqrt{50 a^3 b^2}$ . This value can be simplified by factoring out the square root of $50 a^3 b^2$ , which gives us $5 a b \sqrt{2 a}$ .
The width of the rectangle is $\sqrt{200 a^3}$ . This value can also be simplified by factoring out the square root of $200 a^3$ , which gives us $10 a \sqrt{2}$ .

Calculating the Perimeter

The perimeter of a rectangle is the sum of the lengths of all its sides. To calculate the perimeter, we need to add the lengths of the two pairs of opposite sides. In this case, the perimeter can be calculated as follows:

\begin{array}{l} 2(\sqrt{50 a^3 b^2} + \sqrt{200 a^3}) \\ = 2 \cdot 5 a b \sqrt{2 a} + 2 \cdot 10 a \sqrt{2} \end{array}

This expression represents the perimeter of the rectangle, which is the sum of the lengths of all its sides.

Simplifying the Expression

To simplify the expression, we can combine like terms. The expression can be rewritten as:

\begin{array}{l} 2 \cdot 5 a b \sqrt{2 a} + 2 \cdot 10 a \sqrt{2} \\ = 10 a b \sqrt{2 a} + 20 a \sqrt{2} \end{array}

This simplified expression represents the perimeter of the rectangle.

Conclusion

In conclusion, the dimensions of the rectangle are $\sqrt{50 a^3 b^2}$ and $\sqrt{200 a^3}$ . The perimeter of the rectangle can be calculated using the formula $2(\sqrt{50 a^3 b^2} + \sqrt{200 a^3})$ . By simplifying the expression, we can rewrite it as $10 a b \sqrt{2 a} + 20 a \sqrt{2}$ . This expression represents the perimeter of the rectangle, which is the sum of the lengths of all its sides.
