(require dmeasurement of) area is that which results by multiplying half the sum of the end measure and the middle moasure by the length
Examples in illustration thereof. 33. In the case of an arcn resembling the coufiguration of a yava grain, the length is 80 and the breadth in the middle is 40. Tell me, what may be the oaloulated measure of that arca P
34. Tell (me what may be the calculated measure of the aron) in relation to a field which has the outline configuration of tho mrdanga, and of which the length is 80 dandax, the end measuro is 20 and the middle measure is 40 dandas.
35. In the case of a field having the outline of tho panava, the length is 77 dandas, the measure of each of the two ends in 8 dandas, and the measure in the middle is 4 dandas. (What is tho measure of the area P)
36. Similarly in the case of a field having the outline of the vajra, the lengtb is 96 dandas, in the middle there is the middle point ; and at the ends tho mensure is 134 dandns. (What is the meaeure of the aroa )
The rule for arriving at the measure of areas such as the ubhaya-nisëdha or di-deficient area :
37. On subtracting the product of the longth into hall the breadth from the produot of the length into the breadth, you
The measures of the area arrived at according to the rule given in this stany. are approximately correct in the case of all the Aguros, as the rulo is based on the wsumption that onch of the bounding curved lines may be taken to be equal to the rim of two straight lines formed by joining the ends of the curven with tho middle point thereof.
87. The figare mentioned in this stanse are those given below:
These are looked apon w being derived from & quadrilateral Agaro which is divided into four triangles by moone of ita diagonale ronging each other. The
