Answer:
10,000 square feet is the maximum size for a building on this slot.
Explanation:
A city lot measures 100 feet x 250 feet. The city zoning ordinance specifies that maximum lot coverage is 40%of the lot.
First we find the total area of city = 100 x 250
Area = 25,000 square feet
Maximum coverage area is 40% of city area
Maximum size of for building on this lot = 40% of 25,000
Now we calculate 40% of 25,000
Maximum size for building = 0.40 x 25000 = 10,000 square feet
Thus, 10,000 square feet is the maximum size for a building on this slot.
