Question

plz solve 13th question

Answer 1

the area of a triangle is =
under root [s (s-a) (s-b) (s-c) ]
here,
s = semiperimeter = 132
a,b,c are the sides of a triangle
here given the product of the difference of the semiperimeter is 13200

now, the area of the triangle will be
under root [ 132 x 13200 ]
=1320 cm square
