Question

121 square feet 

 

 

2.00$ and foot

Answer 1

121 happens to be a perfect square, 11²

therefore the side length of the square is 11.

 

I must point out that the plural of foot is FEET.

 

I can make no sense of the remark you included:  2.00$ and foot

Answer 2

121 ft² are in 121 ft².

 

No "foots" in 121 ft²
