<h3><u>Question:</u></h3>
The perimeter of a rectangle is 34 units. Its width W is 6.5 units.
Write an equation to represent the perimeter in terms of the length L, and find the value of L
<h3><u>Answer:</u></h3>
The length of rectangle is 10.5 units
<h3><u>
Solution:</u></h3>
Given that,
Perimeter of rectangle = 34 units
Width of rectangle = 6.5 units
Let "L" be the length of rectangle
<em><u>The perimeter of rectangle is given by formula:</u></em>
Perimeter = 2(length + width)
<em><u>Substituting the values we get,</u></em>
![34 = 2(L + 6.5)](https://tex.z-dn.net/?f=34%20%3D%202%28L%20%2B%206.5%29)
Thus the equation is found
<em><u>Solve for "L"</u></em>
![L + 6.5 = \frac{34}{2}\\\\L + 6.5 = 17\\\\L = 17 - 6.5\\\\L =10.5](https://tex.z-dn.net/?f=L%20%2B%206.5%20%3D%20%5Cfrac%7B34%7D%7B2%7D%5C%5C%5C%5CL%20%2B%206.5%20%3D%2017%5C%5C%5C%5CL%20%3D%2017%20-%206.5%5C%5C%5C%5CL%20%3D10.5)
Thus length of rectangle is 10.5 units
20% of 3km is 0.6 Kilometer
