Question

the area of triangle whose sides are 4cm,13cm and 15cm is ​

Answer 1

Answer:

let the sides of triangle be a=4cm, b=13cm, c=15cm

semiperimeter of triangle=s=a+b+c/2

                                              =4+13+15=32/2=16

area of triangle=under root s(s-a)(s-b)(s-c)

=under root 16(16-4)(16-13)(16-15)

=under root 16(12)(3)(1)

=under root 16 x 36

=under root576

=24 sq cm
