Step-by-step explanation:
Let the sides be 2x,6xand7x
perimeter of a ∆=side +side+side
=>300m=2x+6x+7x
=>300m=18x
=>300/18= x
=>16.6= x
Therefore,
side 1= 2x =2* 16.6 =33.2m
side 2= 6x=6"16.6= 99.6m
side 3=7x=7*16.6= 116.2m
Now, UNITS IN CENTIMETERS
33.2m=3320cm
99.6m=9960cm
116.2m=1162cm
(1m=1*100cm)
