Difference between the length &breadth of a rectangle is 30 m. If its perimeter is 300 m, then its area is?? We have: (l - b) = 30 and 2(l + b) = 300 or (l + b) = 150? Choose the correct choice from the following options:
A) 3:5
B) 2:3
C) 3:6
D) 3:4
E) 3:2
Solving the two equations, we get: l = 90 and b = 60.   The ratio of length and breath is 90:60 =3:2   3:2
