STEP BY STEP EXPLANATION-
Let us consider ratio values as 8x,15x,17x
Now let’s add these values 8x+15x+17x=40x
Here8x is the height,15xis the base
Perimeter =160cm
So x=160/40
=4cm
Now the measurements are 40cm,60cm,68cm
Here 40 is height,60is base
Area of triangle is 1/2 x base x height
=1/2 x 40 x 60
=1200 cm square
