Given that :- ratio of length of side of triangle=5:6:7
perimeter of triangle=72cm
let the length of side of triangle be 5x,6x,7x
now we know that , perimeter of triangle=a+b+c where a= length of one side of triangle, b= length of another side of triangle, c=base of triangle
now, 72=5x+6x+7x
18x=72
x=72/18
x=4
length of one side=5x =5*4=20cm
length of base=6x =6*4=24cm
length of another side=7x =7*4=28cm
