Given,
area of rectangular room=165sq.m
breadth of rectangular room=x
length of rectangular room=4x
area=length.breadth
4x into x=165sq.m
4x^2=165sq.m
x^2=165/4
x^2=41.25
x=root 41.25
x=6.422
since,breadth of rectangular room=6.422sq.m
length of rectangular room=4x=4 into 6.422=25.688sq.m
area of rectangular room=165sq.m
