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
