Question

#### Dimensions:
- **Parking Lot:**
- Width: 22.5 cm
- Height: 16.5 cm
- **Building:**
- Width: 12.0 cm
- Height: 12.0 cm
#### Scale:
1 cm = 6 ft
#### Question:
What is the area of the parking lot?
#### Step-by-Step Solution:
1. **Convert the dimensions from cm to ft using the given scale:**
- For the parking lot:
- Width = 22.5 cm × 6 ft/cm = 135 ft
- Height = 16.5 cm × 6 ft/cm = 99 ft
- For the building:
- Width = 12.0 cm × 6 ft/cm = 72 ft
- Height = 12.0 cm × 6 ft/cm = 72 ft
2. **Calculate the area using the dimensions in feet:**
- Area of the parking lot \( = \text{Width} \times \text{Height} = 135 \, \text{ft} \times 99 \, \text{ft} = 13,365 \, \text{ft}^2 \)
- Area of the building \( = \text{Width} \times \text{Height} = 72 \, \text{ft} \times 72 \, \text{ft} = 5,184 \, \text{ft}^2 \)
3. **Subtract the area of the building from the total area of the parking lot:**
- Area of the parking lot (excluding the building) \( = 13,365 \, \text{ft}^2 - 5,184 \, \text{ft}^2 = 8,181 \, \text{ft}^2 \)
#### Answer:
The area of the parking lot is **8,181.0 ft²**.
##### Additional Explanation of the Diagram:
- A large rectangle represents the parking lot.
- A smaller, inner rectangle represents the building.
- Dimensions are clearly marked, and the scale is provided for conversion.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1baf9202-e59e-43c4-a434-dbe99667a408%2Ffc0788cb-5973-46ca-b98b-2881a622e93e%2Flj12lyd.png&w=3840&q=75)
Transcribed Image Text:### Calculating the Area of a Parking Lot
The diagram below represents a scale drawing of a building and the adjacent parking lot. The scale used for this drawing is 1 cm = 6 ft.

#### Dimensions:
- **Parking Lot:**
- Width: 22.5 cm
- Height: 16.5 cm
- **Building:**
- Width: 12.0 cm
- Height: 12.0 cm
#### Scale:
1 cm = 6 ft

3. **Subtract the area of the building from the total area of the parking lot:**
- Area of the parking lot (excluding the building) \( = 13,365 \, \text{ft}^2 - 5,184 \, \text{ft}^2 = 8,181 \, \text{ft}^2 \)
#### Answer:
The area of the parking lot is **8,181.0 ft²**.
##### Additional Explanation of the Diagram:
- A large rectangle represents the parking lot.
