How many square feet is 14 feet?

Answer 1

There can be no conversion.

A foot is a measure of length in 1-dimensional space while a square foot is a measure of area in 2-dimensional space. The two measure different characteristics and, according to the most basic principles of dimensional analysis, any attempts at comparisons or conversions between the two are fundamentally flawed.

Answer 2

14 feet is a linear measurement. As such it has no width

area = length × width = 14 ft × 0 ft = 0 SQUARE feet.

Answer 3
