Question

The sides of a triangle are in the ratio 1/2:1/3: 1/4 and its the perimeter is 130 cm . what os the lenght of the longest sides​

Answer 1

Let the variable is "x"

So according to the question;

The three sides of the triangle will be,

= x/2 ; x/3 ; x/4

And the total perimeter of the triangle is 104 cm

So;

x/2 + x/3 + x/4 = 104

6x+4x+3x / 12 = 104

13x/12 = 104

x= 104×12 /13

x= 96

The length of the three sides will be;

= x/2 cm ; x/3 cm ; x/4 cm

= 48 cm ; 32 cm ; 28 cm

Length of the longest sid48cm
