A boat builder made a sail for a yacht. What is the area of the boat's sail? (Use the formula A = 1/2 bh, where b is the base and h is the height)

To arrive at an area of 50 ft squared, the dimensions used must be incorrect or the calculation misapplied. For instance, if the base and height values were both too small or improperly substituted, this would yield a significantly lower area than what is accurate.

An area of 100 ft squared would imply either a larger base or height than what is specified or an erroneous calculation. For example, if one incorrectly used base = 10 ft and height = 20 ft, it would yield A = 1/2 * 10 * 20 = 100 ft squared, which does not align with the actual dimensions provided in the problem.

This area exceeds the calculated values when applying the formula. It suggests an incorrect interpretation of either the base or height measurements leading to an inflated area. For instance, using a base of 15 ft and height of 20 ft would yield A = 1/2 * 15 * 20 = 150 ft squared, which does not reflect the actual dimensions given.
