Answer»

Answer:

4 , 6 , 9

Step-by-step explanation:

given

sides of a TRIANGLE are in the ratios 1:1.5:2

PERIMETER is 18 cm

to find

length of each side

assumption

let the RATIO be in terms  of x

solution

sides of triangle are x, 1.5x, 2x

perimeter = x + 1.5x + 2x

                 = 4.5x

given perimeter = 18

therefore 4.5x = 18

===> x = 4

1.5x = 6

2x = 9
