FOR A RECTANCLE TO ENCLOSE THE MAXIMUM AREA IT SHOULD BE A SQUARE. THUS THREE SIDES OF THE SQUARE HERE WOULD TOTAL 50+2=52 FEET (FENCE + GATE)
SEEING AS THERE ARE ONLY THREE SIDES, THE HOUSE BEING THE FOURTH SIDE. WE DIVIDE 52 BY 3=17 1/3 FEET PER SIDE (LENGTH & WIDTH).
17.333*17.333=300.444 SQUARE FEET IS THE MAXIMUM FOR THE AREA ENCLOSED.
