    112.5 square feet

    Step-by-step explanation:

    The scale model is 6 x 3 and the actual patio is 15 x W

    By the definition of a scale model,

    15/6 = W/3

    15 = 2W multiply both sides by 6

    15/2 = W divide both sides by 2

    Area of the patio = length * width

    Area = 15 feet * 15/2 feet = 225/2 square feet = 112.5 square feet
