Lake Texcoco, which became Tenochtitlán is now entirely gone because Mexico City is there. It covered an area of 2.1 x 10^3 square miles. Lake Titicaca in Bolivia, covers an area of 3.232 x 10^4 square miles. About how many times as great is the area covered by Lake Titicaca as opposed to the Lake that the Aztecs built on?
To solve the question, we will estimate how many times Titicaca was larger than Texcoco. Here we shall use the formula: (Area of Titicaca)/(Area of Texcoco) Area of Titicaca=3.232×10^4 Area of Texcoco=2.1×10^3 thus the number of times as great is the area covered by Lake Titicaca as opposed to the Lake that the Aztecs built on (3.232×10^4)/(2.1×10^3) =15.391 times
