Subdividing a 4.5 acre tract

Question

A builder is subdividing a 4.5 acre tract into 50' x 100’ lots. After allowing 71,020 square feet for streets, into how many lots can the tract be divided? 

Answer 1

Step 1: Convert acres to square feet

1 acre = 43,560 sq ft

So:

4.5 acres × 43,560 = 196,020 sq ft

Step 2: Subtract land used for streets

196,020 − 71,020 = 125,000 sq ft remaining

Step 3: Find the size of each lot

Each lot = 50 ft × 100 ft = 5,000 sq ft

Step 4: Divide total usable land by lot size

125,000 ÷ 5,000 = 25 lots

Final Answer: 25 lots
