To determine the original dimensions and area of the rectangle from the scale drawing, we need to convert the dimensions given (length and width) into feet using the scale provided.

  1. Length in units: 7 units

    • Since each unit represents 0.25 feet: \[ \text{Original length} = 7 \text{ units} \times 0.25 \text{ feet/unit} = 1.75 \text{ feet} \]
  2. Width in units: 3 units

    • Again, using the same scale: \[ \text{Original width} = 3 \text{ units} \times 0.25 \text{ feet/unit} = 0.75 \text{ feet} \]
  3. Area: To find the area of a rectangle, we use the formula: \[ \text{Area} = \text{Length} \times \text{Width} \] Plugging in the values: \[ \text{Original area} = 1.75 \text{ feet} \times 0.75 \text{ feet} = 1.3125 \text{ square feet} \]

So, the final answers are:

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