D.

25

Correct option is D

GIVEN:
the length and breadth of a rectangular field are in the ratio 6:5 and the perimeter of the field is 110 m
Solution:
Let the length and breadth of a rectangular field be 6x and 5x respectively.
2 (length +breadth) = 110
2(6x+5x) = 110
2 × 11x =110
x = 110/22
x = 5
Breadth = 5x
5×5 = 25m
