wait for picture to load, hope you can see it!
Additional Solution/Explanation:
Area not occupied by the house is equal to the Area of the shaded as seen in the attached picture.
so this is the equation to solve for the shaded area,
Area of Shaded = Area of Lot - Area of House
Area of Shaded = (25)(20) - (18)(12)
Area of Shaded = 500 - 216
Area of Shaded = 284 sq.mtr
