Final answer:
John did not buy enough deck boards as he purchased 27.9 square meters while the plans call for 28 square meters.
Step-by-step explanation:
To determine if John bought enough deck boards, we need to convert his purchase from square feet to square meters. Using the conversion factor given (1 ft2 = 0.093m²), we can calculate:
300 ft² * 0.093m²/ft² = 27.9 m²
Therefore, John bought 27.9 square meters of deck boards. Since the plans call for 28 square meters, John did not buy enough. He would need to purchase additional deck boards to meet the required amount.
