    452.4 ft²

    Step-by-step explanation:

    The radius on the blueprint is (18 cm) / 2 = 9 cm, so the actual radius will be ...

    radius / (9 cm) = (4 ft) / (3 cm)

    radius = (9 cm) (4 ft) / (3 cm) = 12 ft

    Then the area of the fountain is ...

    A = πr² = π (12 ft) ² = 144π ft²

    The area is about 452.4 ft².
