Problem Statement

Let ABC\triangle ABC be a right triangle with C=90\angle C=90^{\circ}. Two squares S1S_1 and S2S_2 are inscribed in the triangle ABCABC such that S1S_1 and ABCABC share a common vertex CC and S2S_2 has one of its sides on ABAB. Suppose that Area(S1)=1+Area(S2)=441\text{Area}(S_1)=1+\text{Area}(S_2)=441, then calculate AC+BCAC+BC
