Answer 1

Answer:

12,15,18 cm

Step-by-step explanation:

A) Perimeter of triangle is a+b+c =45 cm

4x+5x+6x=45 cm;. 15x=45

Therefore x=3 cm

So, 4x=4*3=12 cm

5x=5*3=15 cm

6x=6*3=18 cm

Answer 2

the ans is 12cm,15cm,18cm,

as perimeter of the triangle is a+b+c

so 12+15+18=45

4x+5x+6x=45 ; 15x=45

x= 45/15 ;x= 3

so: 4x=4×3= 12cm

5x=5×3=15cm

6x=6×3=18cm
