Indian mathematician Brahmagupta had given the formula ‘’ root over (s-a)(s-b)(s-c)(s-d) where s=a+b+c+d/2
so now s=25+60+60+75/2=110
area of quadrilateral
area of quadrilateral
= root over (110-25)(110-60)(110-60)(110-75)
= root over (85)(50)(50)(35)
=root over 7437500
=2727.18 approximately.
I hope that this answer would be correct and helpful to you.
