SOLUTION
Let,
Breadth of the rectangular field = b
•°• Length of the rectangular field = 4b
Given,
Perimeter of the rectangular field = 900 m
According to the question,
2 ( length + breadth ) = 900
=> length + breadth = 900 / 2
=> length + breadth = 450
=> 4b + b = 450
=> 5b = 450
=> b = 450 / 5
•°• b = 90
=> 4b = 4 × 90 = 360
Hence ,
Length of the rectangular field = 360 m
And ,
Breadth of the rectangular field = 90 m
