# Mensuration of quadrilaterals in the L\={\i}l\=avat\={\i}

## TL;DR

This paper explores the historical development of mensuration techniques for quadrilaterals in the L ext={ extcrh}l ext={ extcrh}vat ext={ extcrh} and related Indian mathematical traditions, highlighting new features introduced in Bh ext={ extcrh}skarac ext={ extcrh}rya's work.

## Contribution

It provides a historical analysis of the evolution of quadrilateral mensuration methods in Indian mathematics, emphasizing novel features in Bh ext={ extcrh}skarac ext={ extcrh}rya's L ext={ extcrh}l ext={ extcrh}vat ext={ extcrh}.

## Key findings

- Identification of new features in Bh ext={ extcrh}skarac ext={ extcrh}rya's mensuration methods
- Historical perspective on Indian quadrilateral mensuration techniques
- Comparison with earlier Siddh ext={ extcrh}nta traditions

## Abstract

Mensuration with quadrilaterals had received attention in the Siddh\=anta tradition at least since Brahmagupta. However, in Bh\=askarac\=arya's L\={\i}l\=avat\={\i} we come across some distinctively new features. In this paper an attempt is made to put the development in historical perspective.
