Answer:

1,125 sq uts

Step-by-step explanation:

☆Given the ratio of length and breadth of a rectangle are in the ratio 9:5

☆Let the actual ratio be 9k:5k

☆Perimeter = 140 cm

I.e. => 2(l+b) = 140

2(9k + 5k) = 140

9k + 5k = 70

14k = 70

▪K = 5

▪So length = 45 and breadth = 25

☆Area = (lb) = (45 × 25) = 1,125 sq units
