Question

find the area of the following triangles in which
a=12cm
b=10cm
c=14cm
​

Answer 1

Answer:

4√6

Step-by-step explanation:

We can solve this by using heron's formula

Answer 2

Answer:

a=12

b=10

c=14

=> s= a+b+c/2

=> s= 12+10+14/2= 36/2 = 18cm

Now, $\sqrt{s (s-a)(s-b)(s-c)}$

=> $\sqrt{18(18-12)(18-10)(18-14)}$

=>$\sqrt{18(6)(8)(4)}$

=>$\sqrt{3456}$

=>2*2*2*3$\sqrt{2*3}$

=>$24\sqrt{6}cm ^{2}$

Step-by-step explanation:

Using Heron's Formula: $\sqrt{s (s-a)(s-b)(s-c)}$
