Asquare plot of land has a building 60ft long and 40ft wide at one corner. the rest of the land outside the building forms a parking lot. if the parking lot area is 12,000ft^2, what is the dimensions of the entire plot of land?

Area of building:

60*40 = 2400 ft²

Total plot area = Area of building + Area of parking lot

A = 12,000 ft² + 2,400 ft² = 14,400 ft²

Area of each side of the square plot of land (s) = √14,400 ft²

s = 120 ft

Plot of land = 120 ft × 120 ft

D. i think it is the savings
