Given , ratio of sides = 3:4:5
Now. 3+4+5 = 12
Perimeter = 24
:. The length of the sides are
Side 1 = 3 x 24/12 = 6cm
Side 2 = 4 x 24/12 = 8cm
Side 3 = 5 x 24 / 12 = 10cm
Now , S = (6+8+10)/2
= 12
Now. By using herons formula
Area = root over S (S - side 1)( S - side 2) ( S - side 3)
= root over 12(12 - 6)(12-8)(12-10)
= root over 12 x 6 x 4 x 2
= root over 576
= 24 cm ²
