A sector of a circle? By different lengths, do you mean the radius varies? If that is what you mean, you could use polar coordinates in which the area would be:

[tex]\frac{1}{2}\int_{\alpha}^{\beta}f(\theta)^{2}d\theta[/tex]

I don't know if this is exactly what you are asking, so maybe someone else can clear it up.
