4. Pedro scans a photograph that is 5 inches wide into his computer. He prints two copies of the photograph.
• Copy 1 is an enlargement of the original photograph with a scale factor of 2.5.
• Copy 2 is a reduction of copy 1 with a scale factor of \( \frac{3}{4} \).
What is the width in inches of copy 2?
5. A scale drawing of a piece of land is shown. In the drawing, 1 inch represents 12 feet on the actual piece of land.
What is the area in square feet of the actual piece of land?
A. 36 square feet
B. 54 square feet
C. 5,184 square feet
D. 7,776 square feet

Answer

  1. To find the width of copy 2, first calculate the width of copy 1:
    Width of copy 1 = 5 inches * 2.5 = 12.5 inches.
    Then, calculate the width of copy 2:
    Width of copy 2 = 12.5 inches * \( \frac{3}{4} \) = 9.375 inches.

  2. The drawing shows a trapezoid with bases of 9 inches and 15 inches, and a height of 2 inches. The area of the trapezoid in the drawing is:
    Area = \( \frac{1}{2} \) * (9 + 15) * 2 = 24 square inches.
    Since 1 inch represents 12 feet, the actual area is:
    Actual area = 24 * 12 * 12 = 3,456 square feet.
    Therefore, the correct answer is not listed among the options provided.
