Answer: (3) 27.2 m
Explanation:-
The length of the rectangle = 13.6 m
The breadth of the rectangle = 3.4 m
Formula-
The area of the rectangle = l x b 
Where, l – length of the rectangle,  b – breadth of the rectangle.
Then, the area of rectangle = 13.6 x 3.4
= 46.26 sq. m.
The area of rectangle = the area of square                        ( according to the question)
Formula-
The area of square = side x side
Then, Side x side = 46.26
Side = 6.8       (square root of both side)
Formula-
The perimeter of square = 4 x side
= 4 x 6.8
= 27.2 m
Hence, the answer is (3) 27.2 m.
