**2.5.** *Māruti and varuṇa vedi.* The *māruti vedi* is also an isosceles trapezium having face 3 *aratnis*, base 4 *aratnis* and altitude 6 *aratnis*. A cord of length 12 *aratnis* is taken and the *nirañchana* mark fixed at 7½ *aratnis* (½ + 2 + 2 + 1½ + 1½ = 7½) from one end; the remaining cord measures 4½ *aratnis* (½ + 1½ + 1½ + 1 = 4½). This satisfies the relation 6² + (4½)² = (7½)², which appears to have been used for the construction of the altar. A similar tedious technique is applied for the construction of the *varuṇa vedi*,a which is an isosceles trapezium having face 1½ *aratnis*, base 2 *aratnis*, and altitude 6 *aratnis*.
