3x +4x +5x =48
12x=48
x= 4
there fore it become a right angle triangle .as it's sides are In ratio of right angle triangle
Area = 1÷2×4×3
=6 cm square
12x=48
x= 4

Let the sides of triangle be 3x 4x and 5x
Perimeter of triangle = Sum of All sides
48cm = 3x + 4x + 5x = 12x
48/12 = x = 4
the three sides are 12cm , 16cm and 20cm
Now Use the Herons formula to find its area .
The area will come 9216 cm^2
