    Given:

    A scale drawing of a rectangular park is 5 inches wide and 7 inches long.

    The actual park is 280 yards long.

    To find:

    The area of the actual park.

    Solution:

    Length of drawing = 7 inches

    Length of actual park = 280 yards

    The scale factor is

    7 inches : 280 yards

    1 inches : 40 yards

    The width of the drawing is 5 inches. So, the width of actual part is

    [tex]40\times 5=200 yards[/tex]

    The area of the actual park is

    [tex]Area=Length \times width[/tex]

    [tex]Area=280\times 200[/tex]

    [tex]Area=56000[/tex]

    Therefore, the area of the actual park is 56000 sq. yards.
