Simply multiply the two numbers to get area. In this case the answer is 625 square feet.
625 square feet.
4250ft
12ft*25ft = 300 square feet
375 square feet
Total square feet: 350.0
A minimum of 300 square feet.
-- 625 on the floor-- 625 more on the ceiling-- many more on the walls; in order to calculate them, weneed to know the height of the ceiling above the floor.Add:Assuming you mean 25ft x 25ft, square feet (area) equals length x width. So, the area = 25ft x 25ft = 625 ft2.
If you mean a 35ft by 25ft room then it is 35*25 = 875 square feet
25*20 = 500 sq. ft
25ft * 15ft = 375 ft2
There are: 25*19 = 475 square feet
25' x 17' = 425 square feet
8 meters
Area = 1,963.5 square feet
