Math Problem Statement

the width is 8 in.

Solution

Thank you for providing the width. Let's calculate the scaled dimensions of the rectangle now that we have both the length and width.

Given Information:

  • Original length of the rectangle: 12 inches
  • Original width of the rectangle: 8 inches
  • Scale factor: 23\frac{2}{3}

Calculating the Scaled Dimensions:

  1. Scaled Length: Scaled Length=Original Length×Scale Factor\text{Scaled Length} = \text{Original Length} \times \text{Scale Factor} Scaled Length=12×23=8 inches\text{Scaled Length} = 12 \times \frac{2}{3} = 8 \text{ inches}

  2. Scaled Width: Scaled Width=Original Width×Scale Factor\text{Scaled Width} = \text{Original Width} \times \text{Scale Factor} Scaled Width=8×23=1635.3 inches\text{Scaled Width} = 8 \times \frac{2}{3} = \frac{16}{3} \approx 5.\overline{3} \text{ inches}

Final Dimensions of the Scale Drawing:

  • Length: 8 inches
  • Width: 163\frac{16}{3} inches, or approximately 5.33 inches.

The dimensions of the scale drawing of the rectangle are 8 inches by 5.33 inches.

Would you like more details on any step or have any questions? Here are some related questions:

  1. What is the area of the scaled rectangle?
  2. How does the perimeter of the scaled rectangle compare to the original?
  3. If the scale factor were 12\frac{1}{2}, what would the new dimensions be?
  4. What is the scale factor if the scaled width needs to be exactly 4 inches?
  5. How do you calculate the dimensions of a rectangle if only the diagonal and scale factor are known?

Tip: To maintain the proportions of a scaled drawing, ensure all measurements are multiplied by the same scale factor.
