What is the most efficient lot size when subdividing 3 acres into 5 equally sized lots?

To determine the most efficient lot size for subdividing 3 acres into 5 equally sized lots, it's important to first understand the total area available and how it can be divided.

3 acres is equivalent to 130,680 square feet. When dividing this total by 5, each lot will have an area of approximately 26,136 square feet. The goal is to find dimensions for each lot that are practical and yield this area.

The dimensions provided in the choices can be calculated to see which one gives a product closest to 26,136 square feet:

• 100' x 195' equals 19,500 square feet.

• 141' x 180' equals 25,380 square feet.

• 207' x 309' equals 64,023 square feet.

• 450' x 501' equals 225,450 square feet.

By evaluating these calculations, it becomes clear that the choice of 141' x 180' comes closest to the desired area for each lot. This lot size most efficiently balances the need for adequate space while ensuring that the subdivision remains practical and within the overall parameters of the 3-acre plot.

Choosing this combination allows for regular development patterns that are easier to manage
