GANITASĀRASANGRAHA. 10. In the case of a scalene trilateral figure, one side is 13 dundus, . the opposite side is 15 dandus; and the basers 14 dandas. So what is the quantitative measure (of the arca) of this (figure) ? 11. In the case of a figure resembling (the medial longitudinal section of) the tusk of an elephant, the length of the outer curve is seen to be 88 dandas; that of the inner curve is (seon to be) 72 dandas; the measure of (the thickness at) the root of the tusk is 30 dandas. (What is the measure of the area ?) 188 12. In the case of an equilateral quadrilateral figure, the sides and the opposite sides (whereof) are eachr 60 dandas in measure, you tell me quickly, O friend, the resulting (quantitative) measure (of the area thereof). 13. In the case of a longish quadrilateral figure here, the length is 61 dandas, the breadth is 32. Give out the practically approxi- mate measure (of the area thereof). 14 In the case of a quadrilateral with two equal sides, the length (as measured along either of the equal sides) is 67 dandas, the breadth of this figure is 38 dandas (at the base) and 33 dandas (at the top. What is the measure of the area of the figure ?) 15. In the case of a quadrilateral figure with three equal sides, (each of these) three sides measures 108 dandus, the (remain- ing side here called) mukha or top-side measures 8 dandas and 3 hastas. Accordingly, tell me, O mathematician (the measure of the area of this figure). 16. In the case of a quadrilateral the sides of which are all unequal, the side forming the base measures 38 dandas, the side forming the top is 32 dandas: one of the lateral sides is 50 dandas and the other is 60 dandas. What is (the area) of this (figure) ? 17. In an annulus, the inner circular boundary measures 30 dandas; the outer circular boundary is seen to be 300. The breadth 11. The shape of the figure mentioned in this stanza seems to be what is given here in the margin. it is intended that this should be treated as a tiilateral figure, and that the area thereof should be found out in accordance. with the rule given in relation to trilateral figures.
