The lengths of the sides of the triangle are $\"\"$ and $\"\"$ .

Conside the sides of triangle is $\"\"$ and $\"\"$ .

Since, $\"\"$ and $\"\"$ .

Herons formula for area of a triangle is $\"image\"$ .

Where $\"image\"$ .

Substitute corresponding values in $\"image\"$ .

$\"\"$

substitute above values in $\"image\"$ .

$\"\"$

Solution :

Area of the triangle is $\"\"$
