In order to answer this problem, we need to find a combination of length and width that would have an area of 65 feet^2 and 36 feet. So far, we know that 65=l*w and 36=2l+2w. The answer is the length is 5 and the width is 13. We can check our work.
5*13=65
2(5)+2(13)=10+26=36
The first person to calculate the circumference of the Earth and coined the word "geography" was Eratosthenes. The man who successfully applied his scientific research to create an illustration of the first world map was Anaximander. The person who invented the globe and argued that the representation of the world as a flat, two-dimensional object was not accurate was Ptolemy. He developed the science of geography, although he was better known for his contributions to mathematics was Eratosthenes. The Greek-derived word "geography" means to describe the Earth is correct. China's greatest contribution to geography was the compass. This allowed you to find out which direction you were going extremely easy. The earliest world map ever found was carved on a Babylonian clay tablet that showed Earth as a flat, circular disk, this is correct. It was believed to be created in 6th century BCE. Ptolemy incorporated topography into his maps, which means that the mountain and valley surfaces would appear on the map. This is correct and is the birth or starting of the topological maps! This early group, the Greeks, were the first to use rational thought or logic while investigating the physical world. It is believed that the science of geography originated with each of the following groups except the British. The British are believed to have no contributions to the science of Geography.
