A scale model of a rectangular patio is 6 feet long a 3 feet wide. The actual patio is 15 feet long. What Is the area of the actual patio?

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
