Answer:
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
You have to use the distance formula which is:
Distance = √(x2 - x1)^2 + (y2 - y1)^2
Using the coordinates given.
D = √(4 - (-2)^2 + (1 - 4)^2
D = √(6)^2 + (-3)^2
D = √36 + 9
D = √45
D = √9 × 5
D = 3√5
