You can put this solution on YOUR website!
a= 13 , b= 14 c=14 ft
area of triangle =sqrt%28s%28s-a%29%28s-b%29%28s-c%29%29
where s =%28a%2Bb%2Bc%29%2F2
s= +%28+13%2B14%2B14%29%2F2
= 41%2F2
=20.5
area=sqrt%28s%28s-a%29%28s-b%29%28s-c%29%29
=20.5%2A%2820.5-13%29%2820.5-14%29%2820.5-14%29
=20.5%2A7.5%2A6.5%2A6.5
=80.597 sq.ft
area = 80.597 square ft
