To determine the original rectangle dimensions and area using the scale provided, we need to convert the length and width measured in scale units to feet.

  1. Original Length:

    • Given scale length = 7 units
    • Each unit represents 0.25 feet. \[ \text{Original Length} = 7 , \text{units} \times 0.25 , \text{feet/unit} = 1.75 , \text{feet} \]
  2. Original Width:

    • Given scale width = 3 units
    • Each unit represents 0.25 feet. \[ \text{Original Width} = 3 , \text{units} \times 0.25 , \text{feet/unit} = 0.75 , \text{feet} \]
  3. Original Area:

    • To find the area, we multiply the original length by the original width: \[ \text{Original Area} = \text{Original Length} \times \text{Original Width} = 1.75 , \text{feet} \times 0.75 , \text{feet} = 1.3125 , \text{square feet} \]

Summary:

  • Original length = 1.75 feet
  • Original width = 0.75 feet
  • Original area = 1.3125 square feet
