  "answer": "To find the area of the billiard table in square metres, we first convert the dimensions from feet to metres.\n\n1.  **Convert the length:**\n    $12 \\text{ feet} \\times 0.3048 \\text{ metres/foot} = 3.6576 \\text{ metres}$\n\n2.  **Convert the width:**\n    $6 \\text{ feet} \\times 0.3048 \\text{ metres/foot} = 1.8288 \\text{ metres}$\n\n3.  **Calculate the area:**\n    $\\text{Area} = \\text{length} \\times \\text{width}$\n    $\\text{Area} = 3.6576 \\text{ m} \\times 1.8288 \\text{ m}$\n    $\\text{Area} = 6.68901888 \\text{ square metres}$\n\n4.  **Round to two decimal places:**\n    The third decimal digit is 8, so we round up the second decimal digit.\n    $6.68901888 \\approx 6.69$\n\nANSWER: 6.69",
