Answer:
400x4 = 1600 feet
* * * * *
The above is pure nonsense. Where on earth did the 4 come from?
In any case the question has no meaningful answer. A foot is a measure of length or distance while a square foot is a measure of area. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
That would be 400 square feet. A square yard is 9 square feet. Divide 400 by 9 and you get 44.4 Square yards.
Just about 400
It is exactly 400 square feet.
400 square feet
400 by 400 feet = 160,000 square feet 160,000 square feet = 3.6730946 acres
400 square ft = 37.16 square m
I'm going to say 400.
20 ft x 20 ft = 400 square ft
400 square feet. This is an easy calculation - just multiply the length in feet by the width in feet. The answer is the number of square feet.
400 square meters are 4.3 thousand square feet.
400 square meters is 4,305.56 square feet.
400 square feet = 44.4 square yards.
