    Answer:

      84.14 square units, total

    Step-by-step explanation:

    Use the formulas for area of the figures you’re interested in.

    Rectangle Area

      A = LW

    Circle Area

      A = πr^2

    __

    Your rectangle area will be …

      A = 5 × 14 = 70 . . . . square units

    The area of a full circle with diameter 6 (radius = 6/2 = 3) will be …

      A = π × 3^2 = 9π

    The area of a semicircle of that size is half that:

      semicircle area = 9π/2 = 4.5π

    Then the total area of the two figures is …

      70 + 4.5π ≈ 70 +14.14 = 84.14 . . . square units
