Question

the sides of a triangle are in the ratio 1/4:1/5:1/3 and its perimeter 141cm. find the length of each side.​

Answer 1

Let the ratios be 1/3x, 1/4 x and 1/5x.We know,Perimeter of a triangle = a+b+c=> 94 = 1/3x+1/4x+1/5x....

rectangle are opposite sides are equal

so we find root squre of 141/94

each sides are calculated like this

now try it by you

Answer 2

Answer:

45cm,36cm,and60cm respectively

Step-by-step explanation:

1/4x+1/5x+1/3x=141

15x+12x+20x =141*60

47x=141*60

x=60*3

x= 180

1/4of x=1/4*180=45cm

1/5 of x=1/5*180=36cm

1/3of x=1/3*180=60cm
