Question

the sides of a triangle are in the ratio 1:1.5:2 and it's perimeter is 18 CM. find the length of each side​

Answer 1

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

Answer 2

Answer:

Step-by-step explanation:

let sides be 1x,1.5x and 2x

so,1x+1.5x+2x=18

4.5x=18

x=18/4.5

x=4 cm

therefore sides are 4,6 and 8 cm
