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 most appropriate option.
A) 3 : 5
B) 2 : 3
C) 3 : 6
D) 3 : 4
E) 3 : 2

Rationale: solving the two equations , we get : l = 90 and b = 60 . the ratio of length and breath is 90 : 60 = 3 : 2 e
Answer: E
