Question

How do you use Heron's formula to determine the area of a triangle with sides of that are 25, 16, and 22 units in length?

Answer 1

Area`=173.636" "`square units

Explanation:

Compute half perimeter
`s=(a+b+c)/2=(25+16+22)/2=63/2`

Area`=sqrt(s(s-a)(s-b)(s-c))`

Area`=sqrt(63/2(63/2-25)(63/2-16)(63/2-22))`

Area`=173.636" "`square units

God bless....I hope the explanation is useful.
