Imagine a huge building made up of many different rooms and pathways, it's called Sumatra. Each room is unique and serves a different purpose, just like the different regions of Sumatra.
The building is made up of different materials like bricks, cement, and steel. In the same way, Sumatra is made up of different landscapes such as forests, mountains, and rivers.
Just like how the building has different ways to get around, such as elevators, stairs, and hallways, Sumatra has different transportation options like roads and waterways.
Overall, Sumatra's architecture is like a complex puzzle that all fits together to create a beautiful and functional space for people to live and work in.
