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 things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.

to calculate square feet you need a 2d shape
Square feet x 0.0929 = square metres
length x width
there are 144 Sq. in. in 1 sq. foot. Therefore you divide sq. in. by 144 = sq. ft. or sq.in./144=sq.ft.
Multiply the number of square meters by 10.7639 to get square feet. In this case, 200 x 10.7639 = 2,152.782 square feet.
