Question 211804
a=22, b=14, and c=30
---
There is a formula to find the area of a triangle using only the given three sides.
{{{A=sqrt(s(s-a)(s-b)(s-c))}}}
where {{{s=(a+b+c)/2}}}
---
Here, s=(22+14+30)/2=33
---
So,
{{{A=sqrt(33(33-22)(33-14)(33-30))}}}
{{{A=sqrt(33*11*9*3)}}}
{{{A=sqrt(33*33*3*3)}}}
A=33*3=<u>99 square units</u>
