    The dimensions are 5.83 inches and 6.67 inches

    Step-by-step explanation:

    * Lets explain how to solve the problem

    - The scale drawing is a ratio between the actual length and

    the drawing length

    - The terms of the ratio must have the same units, then the terms

    of the scale drawing must have same units

    * Lets solve the problem

    - 1 inch represents 12 feet

    ∵ 1 foot = 12 inches

    ∴ 12 feet = 12 * 12 = 144 inches

    ∴ The scale drawing is 1 : 144

    - That means 1 inch in drawing represents 144 inches in actual

    ∵ The dimensions are 70 feet by 80 feet

    ∴ 70 feet = 70 * 12 = 840 inches

    ∴ 80 feet = 80 * 12 = 960 inches

    ∵ The scale drawing = 1 : 144

    ∵ The actual dimensions are 840 inches and 960 inches

    ∴ 1 : 144

    ? : 840

    ? : 960

    ∴ 70 feet = 5.83 inches

    ∴ 80 feet = 6.67 inches

    * The dimensions are 5.83 inches and 6.67 inches
