Given:-
- Length = 6 × Breadth
- Area of the rectangular field = 40344 cm²
To find:-
- Perimeter of the rectangular field
Solution:-
Area of the field = 40344 cm²
L × B = 40344 cm²
6B × B = 40344
6B² = 40344
B² = 40344/6
B² = 6724
B² = 82²
B = 82
Perimeter of the field = 2 ( L+B )
= 2 ( 6B + B )
= 2 [ 6(82) + 82 ]
= 2 ( 492 + 82 )
= 2 × 574
= 1148 cm.
Therefore, the perimetre of the rectangular field is 1148 cm.
