Using a 60m long wire mash we shall fence a rectangular garden with two inner walls (see the picture). What will the dimensions a and b of the garden be, if there is 2m wide opening in one outside wall and the area of the garden shall be as large as possible? (The wire mesh is used to make inner walls as well.)
a=7.75m, b=15.5m
a=7.25m, b=16.5m
a=7.5m, b=16m
a=10m, b=11m
