The correct answer is
5356
5356 is correct.
A rhombus has four equal sides, and its two diagonals split it into four congruent right triangles.
The diagonals of a rhombus bisect each other at right angles, so its area \(=\dfrac{1}{2}\times d_1\times d_2\).
\(\dfrac{1}{2}\times 103\times 104=103\times 52=5356\) cm².
