The correct answer is

1225

Evaluate the known square roots first: \(\sqrt{2601} = 51\), \(\sqrt{1089} = 33\) and \(\sqrt{324} = 18\).

Substitute these values into the equation: \(\sqrt{x} \times 51 = (33 + 18) \times 35\).

Simplify the right side: \(33 + 18 = 51\), so \(\sqrt{x} \times 51 = 51 \times 35\).

Divide both sides by 51: \(\sqrt{x} = 35\).

Square both sides: \(x = 35^2 = 1225\).

Hence, the value of \(x\) is 1225.
