let the breadth of rectangle = x metre
then the length = 5x metre
perimeter=168metres
A.T.Q:
perimeter=2(l+b)
168=2(5x+x)
168=2(6x)
168=12x
168/12=x
14m=x
So,breadth=14m
length=5×14=70m
then the length = 5x metre
perimeter=168metres
A.T.Q:
perimeter=2(l+b)
168=2(5x+x)
168=2(6x)
168=12x
168/12=x
14m=x
So,breadth=14m
length=5×14=70m
