c8.t8.13

**10.4-10.9.** *The body*: A rectangle *ABCD* is drawn with *AB* equal to 2 *pu.* or 240 *aṅg.* and *AD* 10 *padas* or 150 *aṅg.* (Fig. 38 (a) ). *FD*, *DG*, *HC*, *CI*, *BJ*, *BK*, *AL* and *AE* are measured out such that each equals 45 *aṅg.* (= 1½ *prakrama*). Join *FG*, *HI*, *JK* and *LE*. *EFGHIJKL* is the body of the altar, with its four corners cut off as laid down in the rule. The area is (240 × 180 - 2 × 45 × 45) sq. *aṅgulas* or ⅞¼ sq. *pu.* The commentator measures the area in a unit of *ṣoḍaśī* which is 1/16 sq. *pu.* or 30 × 30 sq. *aṅgulas*, also called a *caturthī*, the area of B₁. In this unit, the area of the body reduces to 35½ *caturthīs*,—*evamātmaśroṇyaṁseṣvardhapañcamāścaturthyo nirastā bhavanti | atha śiṣṭā ardhaṣaṣṭhāstriṁśaccaturthyo bhavanti* |—*D.*
