the ratio 5:4 which implies that the length is a quarter longer than the breadth (1.25 times). This ratio was commonly used in the town planning of Harappan cities in the third millennium BC. The city of Dholavira in Gujarat, for example, is 771 metres by 617 metres. Over a thousand years later, the same ratio appears in Hindu texts like the Shatapatha Brahmana and Shulbha Sutra that use the ratio in their precise instructions on how to build fire-altars for Vedic ceremonies.
