One acre will be divided into six equal lots. The lots are parallel to each other, rectangular in shape, and 55 feet wide. What is the depth of each lot, in feet?

This choice represents a depth that, when multiplied by the width of 55 feet, does not yield the correct area for the six lots. Specifically, 106 feet would result in an area of 5,830 square feet per lot, totaling only 34,980 square feet for all six lots, which is insufficient compared to the total area of an acre.

Choosing 132 feet for the depth results in an area of 7,260 square feet per lot. Multiplying this by six lots gives a total area of 43,560 square feet, which matches an acre. However, this is not the correct answer since the calculations reveal that a depth of 158 feet is necessary to maintain the correct area distribution for the lots.

This depth produces an area of 10,340 square feet per lot, leading to a total area of 62,040 square feet for all six lots. This far exceeds the area of one acre and confirms that this choice is incorrect, as it suggests a greater lot size than permissible.
