Answer:

hey buddy the answer to your question is given below with the explanation hope it helps

Step-by-step explanation:

s=(8+15+17)/2=20.

area of triangle =square root of (s(s-8)(s-15)(s-17))

=square root of(20(20-8)(20-15)(20-17)

=square root of(20*12*5*3)

= square root of(4*5*4*3*5*3)

=4*5*3=60cm^2.
