Question

The shape of a farm is a quadrilateri. Measurements taken of the farm, by
naming its corners as P, Q, R, S in order are as follows l(PQ) = 170m , l(QR) = 259m
l(RS) = 100 m, I(PS) = 240 m, l(PR) = 260n.
Find the area of the field in hectare ( 1 hectare = 10,000 sq. m) ​

Answer 1

Answer:

hi, this can be done by drawing the diagonal and then applying the herons formula on both the triangles, i expect u can do this much. Formula for herons formula is

$\sqrt{s(s - a)(s - b)(s - c)}$

where s is semi perimeter ( perimeter/2)
