Answer :
Explanation:
To provide information on the Seven Wonders of the World based on the parameters you've specified, here's a detailed breakdown:
### 1. Dimensions of the Structure
1. **Great Wall of China**
- Length: Approximately 21,196 km (13,171 miles)
2. **Petra, Jordan**
- City area: Approximately 264 square km (102 square miles)
3. **Christ the Redeemer, Brazil**
- Height: 30 meters (98 feet)
4. **Machu Picchu, Peru**
- Area: Approximately 13 square km (5 square miles)
5. **Chichen Itza, Mexico**
- Pyramid height: 24 meters (79 feet)
6. **Roman Colosseum, Italy**
- Dimensions: 189 meters by 156 meters (620 feet by 512 feet)
7. **Taj Mahal, India**
- Dimensions: 58 meters by 56 meters (190 feet by 184 feet)
### 2. Time Period Required to Build
- **Great Wall of China**: Construction started in 7th century BC, with continuous enhancements until 16th century AD.
- **Petra, Jordan**: Developed around 5th century BC.
- **Christ the Redeemer, Brazil**: Built between 1922 and 1931.
- **Machu Picchu, Peru**: Estimated to have been built around 1450 AD.
- **Chichen Itza, Mexico**: Built over several centuries, with major constructions from 600 to 1200 AD.
- **Roman Colosseum, Italy**: Completed in 80 AD.
- **Taj Mahal, India**: Constructed between 1632 and 1653.
### 3. Comparison of Area Using Bar Graph
- A bar graph can visually represent the comparative area sizes of each wonder. For example, the Great Wall of China would have the longest bar due to its extensive length compared to the others, whereas Christ the Redeemer's bar would be relatively shorter due to its height-based dimension.
### 4. Comparison on Number of Visitors During the Last 3 Years Using Bar Graph
- Each wonder attracts varying numbers of visitors annually. The Taj Mahal, for instance, receives millions each year, while Petra sees hundreds of thousands. A bar graph could show these visitor numbers over the past three years for each wonder.
### 5. Symmetry as a Main Feature
- **Symmetry** is a significant aspect of all Seven Wonders:
- **Great Wall of China**: Symmetrical in its design and structure across its entire length.
- **Petra, Jordan**: Symmetrical in its architectural layout and intricate carvings.
- **Christ the Redeemer, Brazil**: Symmetrical in its arms outstretched pose and architectural balance.
- **Machu Picchu, Peru**: Symmetrical in its urban planning and integration with natural surroundings.
- **Chichen Itza, Mexico**: Symmetrical in its pyramid design and alignment with celestial events.
- **Roman Colosseum, Italy**: Symmetrical in its amphitheater layout and architectural precision.
- **Taj Mahal, India**: Symmetrical in its mausoleum design and garden layout.
Symmetry enhances the aesthetic appeal and structural stability of these wonders, contributing to their enduring status as marvels of architecture and engineering.
These parameters provide a comprehensive overview of the Seven Wonders of the World, highlighting their dimensions, construction times, visitor statistics, and the role of symmetry in their design.
