Answer 1

Answer:

i dont think so this is the correct question

but i solved how much ever i can

hope it helped u

if so please mark me as the brainliest

thanks:)

Step-by-step explanation:

a=10, b=15,c=12

semi perimeter=10+15+12/2

                         =37/2

                        s =18.5

ar. of triangle=√s(s-a)(s-b)(s-c)

=√18.5(18.5-10)(18.5-15)(18.5-12)

=√18.5(8.5)(3.5)(6.5)

=√3577.4375
