The Shulbasutras of Baudhayana, Apastamba, Katyayana and Manava: With Text, English Translation and Commentary c8.t28.6

c8.t28.6

**18.4.** *The body.* It agrees with the body of the first type of falcon not only in area but also in shape (vide 15.7, 16.1). It is only differently described. One starts with the same rectangle of breadth 1½ *pu.* or 180 *aṅg.* and length 2 *pu.* or 240 *aṅg.* The four corners are cut off, each by an isosceles right triangle of side 60 *aṅg.* (Fig. 15(b)). The area of each such triangle is 1800 sq. *aṅg.* equivalent of 2 *ṣoḍaśī* bricks, so that a total of 8 bricks are taken out from 48 bricks that the rectangle holds, leaving an area equivalent of 40 bricks. Regarding the cutting of the corners, Kapardi advises the construction of 4 squares of side ½ *pu.* and cutting them off diagonally—*yathā śroṇyaṁseṣu catvāri caturaśrāṇi ardhapuruṣapramāṇāni kṛtvā akṣṇayānyārdhāni nirasyet.*
