Step-by-step explanation:

let the ratio be

3x:4x:5x

perimeter of triangle = 3x + 4x +5x

144= 12x

12 = x

then,

3x = 3 ×12

= 36

4x = 4×12

48

5x = 5×12

60

i)

area \: of \: triangle =  \frac{1}{2}  \times b \times h \\  \\  =  \frac{1}{2}  \times 36 \times 48 \\  \\  = 18 \times 48 \\  \\  = 864

ii)

hypotheses is the longest side

so the answer is 60.

I think so this is the answer.
