how do u get sq ft out of feet ..25ft by 20ft = ------sqft?

Question

a roof is 25' by 20' how many sqft is there and do u x 25 by 20 to get the answer.

Answer 1

Yes you multiply 25x20=500 square feet. Roofs are figured by per sq..10'x10' so....if 10x10=100 sq...then 100x5=500 you have 5 sq. Always buy more shingles due to cuts that will be made when putting on roof valleys etc. Hope I was of help. Good luck with the roof.

Answer 2

25 x 20 = 500, however, roofing is estimated in squares, 1 sq. being 10' x 10' so you would have 5 sq.

Answer 3

what percentage sq. feet is determined by technique of multiplying length by technique of width. E.g., a 12' X 14' room might want to be (12 X 14 = 168 sq. feet). 20 sq. feet might want to be the equivalent of four' X 5'. So, in case your room is 12' X 14' (168 squaretoes) you may want to need 9 bins (20 X 9 = one hundred eighty)

Answer 4

Its 500 sq ft. Divide by 9 and you have sq yards

Answer 5

25 x 20 = 500sq ft. if your getting shingles buy an extra 2 bundles

Answer 6

20 x 25 =500 square feet. foot x foot = square feet. Any unit multiplied the same is square. if it is multiplied again by the same unit it will be cubic.

Answer 7

Yes.Multiply 25 x 20 = well you do the sum!

9sq.ft.=1sq.yd.
