Finding the Side Length of a Rhombus Given Area and a Diagonal
If you're dealing with a rhombus and need to find the side length given the area and one of its diagonals, there are specific formulas and steps you can follow. This guide will walk you through the process and provide a detailed example.
Formula Overview
To find the side length of a rhombus, you can use the following formulas:
1. Area of a Rhombus:
The area ( A ) of a rhombus can be calculated using the formula:
[ A frac{d_1 times d_2}{2} ]Where ( d_1 ) and ( d_2 ) are the lengths of the diagonals of the rhombus.
2. Side Length of a Rhombus:
The relationship between the diagonals and the sides of the rhombus can be expressed as:
[ s sqrt{left(frac{d_1}{2}right)^2 left(frac{d_2}{2}right)^2} ]Where ( s ) is the length of a side of the rhombus.
Step-by-Step Example
Consider a rhombus where the area ( A ) is 84 square meters and one diagonal ( d_1 ) is 24 meters. We need to find the side length of the rhombus.
Step 1: Find the Length of the Second Diagonal ( d_2 )
Using the area formula:
[ 84 frac{24 times d_2}{2} ]Solving for ( d_2 ), we get:
[ 84 12 times d_2 ] [ d_2 frac{84}{12} 7 text{ meters} ]Step 2: Calculate the Side Length ( s )
Now, we can use the relationship between the diagonals and the sides to find the side length:
[ s sqrt{left(frac{24}{2}right)^2 left(frac{7}{2}right)^2} ]Substituting the values, we get:
[ s sqrt{12^2 - 3.5^2} sqrt{144 12.25} sqrt{156.25} ]Therefore, the side length ( s ) is:
[ s 12.5 text{ meters} ]Conclusion
The length of a side of the rhombus is 12.5 meters.
Additional Information About Rhombus
A rhombus is a special type of quadrilateral where all four sides are of equal length. Here are a few additional points about rhombus properties and applications:
Properties of a Rhombus
All sides are equal in length. The diagonals bisect each other at right angles (90 degrees). Opposite angles are equal. The diagonals are not equal in length.Applications of Rhombus in Real Life
Rhombus shapes can be found in various real-life applications, such as:
