Question

Using heron's formula the area of a triangle whose sides are 13 cm,13 cm,and 6cm​

Answer 1

Answer:

Semi-perimeter =13+13+6/2

= 16 cm

Area of the triangle (according to the Heron's Formula)

√3*3*10*16

=√1440 cm sqr.

Answer 2

Answer:

Step-by-step explanation:

a=13,b=13,c=6

s=a+b+c/2

13+13+6/2

32/2=16

(s-a)=16-13=3

(s-b)=16-13=3

(s-c)=16-6=10

√s(s-a)(s-b)(s-c)

√16(3)(3)(10)

√2×2×2×2×3×3×2×5

2×2×3√10

12√10
