The width, labelled x in the figure is 162.5 meters
<h3>How to determine the width of the rectangle?</h3>
From the question, we have the following parameters that can be used in our computation:
Length = 650 - 2x
Width = x
The area of a rectangle is the product of its dimensions
So, we have
Area = Length x Width
Substitute the known values in the above equation, so, we have the following representation
A = (650 - 2x) * x
Evaluate
A = 650x - 2x²
Differentiate and set to 0
650 - 4x = 0
So, we have
4x = 650
Divide by 4
x = 162.5
Hence, the width is 162.5 meters
