Expert Answer
Let l be length of rectangle and l/2 is its breadth.
Length of wire to be cut to form the above rectangle = 2 [ l + (l/2) ] = 3l
remaining length of wire to form square = 34 - 3l
side of the squire to be formed = (34 - 3l)/4
Area A 
Let us differentiate the relation for area and equate it to zero to get minimum area
hence 
.....................(1)
.....................(1)By solving the above eqn.(1), we get l = 6 m
Required length of wire to form rectangle = 18 m
Required length of wire to from square = 16 m
