Question

the perimeter of a triangle is 36 cm. if the sides of triangle are in ratio 2:3:4, then longest side is.....​

Answer 1

Answer:

RATIO OF SIDES =2:3:4

=LET THE SIDE BE 2X,3X AND 4X

THERE FORE , 2X+3X+4X=36CM

=9X=36

=X=36/9

=X=4

=SIDE 1=2*4=8CM

=SIDE 2=3*4=12CM

=SIDE 3=4*4=16CM

THERE FORE, LONGEST SIDE =16CM

Answer 2

Answer:

GIVEN:-

✒Perimeter of triangle = 36cm

✒Sides = 2:3:4

_____________________

Now,

Let the sides be 2x,3x,4x

Perimeter of triangle = Sum of all three sides

2x+3x+4x = 36cm

9x = 36cm

x = 36/9 cm

= 4 cm

Sides = 8cm,12cm,16cm

______________________

Longest side = 16cm
