Answer:
The width is: 
The length is 
Step-by-step explanation:
The given rectangle has area given algebraically by the function:
The width of the rectangle is the greatest common factor of 
, 
and 
That is the width is:
We now divide the area by the width to obtain the length of the rectangle:
This simplifies to:
Answer:
2tanθ = 2cotθ
tanθ = cotθ
tanθ = 1 /tanθ
tan²θ = 1
tanθ = ±1
if tanθ = 1
θ = 45° + nπ (π = 180° , n is a natural number)
if tanθ = -1
θ = 135° + nπ
