The length of the rectangle is determined as x - 5 while the width is x² + 3.
<h3>
Length of the rectangle</h3>
The length of the rectangle is determined by the following formula shown below;
Area = Length x width
L = A/w
x - 5
------------------------------------
x² + 3 √x³ - 5x² + 3x - 15
-(x³ + 3x)
--------------------------
- 5x² - 15
-5x² - 15
----------------------------
0
Thus, the length of the rectangle is determined as x - 5 while the width is x² + 3.
