To find the area of the dilated rectangle, we first need to determine the dimensions of the original rectangle and then apply the scale factor to them.

  1. Original dimensions:

    • Height = 6 inches
    • Base (width) = 8 inches
  2. Area of the original rectangle: \[ \text{Area} = \text{Height} \times \text{Base} = 6 , \text{inches} \times 8 , \text{inches} = 48 , \text{square inches} \]

  3. Applying the scale factor: The scale factor is 0.5, which means each dimension will be multiplied by 0.5:

    • New height = \( 6 \times 0.5 = 3 \) inches
    • New base = \( 8 \times 0.5 = 4 \) inches
  4. Area of the dilated rectangle: \[ \text{Area} = \text{New Height} \times \text{New Base} = 3 , \text{inches} \times 4 , \text{inches} = 12 , \text{square inches} \]

The area of the dilated rectangle is 12 square inches.
