It is very simple
5x+12x+13x=300cm(perimeter)
30x=300
X=10
So,5x=50,12x=120,13x=130cm
S= semi perimeter =300/2 =150cm
Area of a triangle =/s(s-a)(s-b)(s-c)
Where a,band c are sides and s is semi perimeter,
=/150(150-50)(150-120)(150-130)
=/150*100*30*20
=3000cm(square)
Area of the triangle is 3000cm,square
5x+12x+13x=300cm(perimeter)
