Answer 1

we must take the three ratios as x so a=3x,b=4x,c=5x it becomes then perimeter of triangle is a+b+c=perimeter of triangle.

so,

3x+4x+5x=96

12x=96

x=96/12

x=8

so,

3x=3×8=24

4x=4×8=32

5x=5×8=40

Answer 2

Answer:

Step-by-step explanation:

Let the sides be 4x 3x 5x

4x + 3x + 5x =96

12x =96

X=8

4*8=32

3*8=24

5*8=40

Heronn formula

S=32+24+40/2 =48

Area= √48(48-32)(48-24)(48-40)

√48*16*24*8

=748
