The points \( (-6,1),(6,10),(9,6) \) and \( (-3,-3) \) are the vertices of a rectangle. If the area of the portion of this rectangle that lies above the \( \mathrm{x} \) axis is \( \mathrm{a} / \mathrm{b} \), find the value of \( (\mathrm{a}+\mathrm{b}) \), given \( \mathrm{a} \) and \( \mathrm{b} \) are coprime.
