Answer:

$\bold{\bigstar{\fbox{\color{cyan}{answer}}}}$

☞ the perimeter of a triangle is = sum of all the sides

☞ given that the perimeter is 13

☞ ratio of all the 3 sides is 2:3:4

☞ let the three sides be x

☞ 2x:3x:4x = 13

☞9x = 13

☞ x= 13/9

$\frac{13}{9} = 1.44$

so each side is

☞ 2×1.44 = 2.44

☞ 3×1.44 = 3.44

☞ 4×1.44 = 4.44
