Question

find the area of the length triangle of whose side are 8cm 24cm and
30​

Answer 1

Step-by-step explanation:

Let 1st side=a

2nd side=b

3rd side =c

Therefore, a+b+c=(8+24+30)cm.

=62cm

Now,½(a+b+c)=½(62)

=31cm.

=s. [Let]

Area of the Triangle=√s(s-a)(s-b)(s-c)

=√31(31-8)(31-24)(31-30)

=√31(23)(7)(1)

=√(31)161

=√4991

=70.65 cm²

Therefore the Required Area is 70.65 cm²
