Question

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?

Answer 1

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
