The formula for the answer is consistant. However the units are variable.
In either case the formula for square feet is as follows:
unit "A" in feet X unit "B" in feet = SQ. FT. Therefore, if in the above example both units "A" and "B" are in feet, the result is ("A" X "B") = SQ. FT.
= 16 X 16 = 256 SQ. FT.
However, the units are in inches the correct result can be computed in either of two ways.
1.. Convert each unit into feet and multiply one by the other
16" X 16" = 1.333' X 1.333'
= 1.778 SQ. FT.
or
2.. Multiply unit "A" in inches by unit "B" in inches and divide by 144
= 16" X 16" = 256 / 144 = 1.778 SQ. FT.
Area of a rectangle is equal to length x width.15 feet x 16 feet = (15 x 16) square feet = 240 square feet
(16" x 16") = 256 square inches(256 square inches) / (144 square inches per square foot) = 1 and 7/9 square feet
Divide both sides by 12 to change to feet:- 8/12 times 16/12 = 8/9 square feet
10' x 16' is not a square but a rectangle and the diagonal is square root of (10^2 + 16^2) = square root of (100 + 256) = square root of 356 which is 18.867 feet

16' x 28' = 448 square feet.
17 feet x 16 feet = 272 square feet
Square feet = length by width ONLY Cubic feet = length by width by height Square feet = 16 x 16 = 256 square feet Cubic feet = 16 x 16 x 16 = 4096 cubic feet
16 feet x 28 feet equals 448 square feet.
256 square feet. (16 x 16 = 256)
16' x 16' = 256 square feet.
256 square feet
36 feet x 16 feet = 576 square feet.
16 feet x 80 feet = 1,280 square feet.
16 x 13 feet has an area of 208 square feet.
10' x 16' = 10*16 = 160 square feet
1.78 square feet
