Given: The area of a square field is 841 sq.m
Since side of square = √Area
So, side of square field =
Thus , side of square field = 29 m
Perimeter of square = 4( side) = 4(29) = 116 m
Let x be the breadth of rectangle then 2x be the length
Perimeter of rectangle = 2 (length+breadth) = 2(2x+x)= 2(3x)=6x
As per question, perimeter of rectangle= Perimeter of square

Length : 
Area of rectangle = length x breadth

Area of rectangle =
