Step-by-step explanation:

Answer 2

Step-by-step explanation:

let the first side of triangle be 2x

let the second side of triangle be 3 x

let the third side of triangle be 4x

A/q

perimeter of triangle = first side + second side + third side

63=2x+3x+4x

63=9x

63/9=x

7=x

so

first side =2x

=2×7

=14

second side=3x

=3×7

=21

third side=4x

=4×7

=28
