Answer:
l = a/(2 w) - (π w)/4
Step-by-step explanation:
Solve for l:
a = 2 l w + (π w^2)/2
a = 2 l w + (π w^2)/2 is equivalent to 2 l w + (π w^2)/2 = a:
2 l w + (π w^2)/2 = a
Subtract (π w^2)/2 from both sides:
2 l w = a - (π w^2)/2
Divide both sides by 2 w:
Answer: l = a/(2 w) - (π w)/4
Answer:
[tex]l=\dfrac{2A-\pi w^2}{4w}[/tex]
Step-by-step explanation:
Subtract terms not containing L, then divide by its coefficient.
[tex]A=\frac{1}{2}\pi w^2+2lw\\\\A-\frac{1}{2}\pi w^2=2lw\\\\l=\dfrac{2A-\pi w^2}{4w}[/tex]
