Answer:

  • field size: 1750 acres
  • developed area: 1400 acres

Step-by-step explanation:

If the developed area is 80% of the field, and the undeveloped area is 20%, then the developed area is 4 times the undeveloped area, so is ...

  developed area = 4 × 350 acres

  developed area = 1400 acres

Then the total area is ...

  total area = developed area + undeveloped area = (1400 +350) acres

  total area = 1750 acres
