try to multiply ft*ft what you always get is ft !!


Finally you acknowledge that ft^2 means ft*ft!! Right?

12 ft^2
Clearly the 12 is not being squared (PEMDAS, look it up). You say ft^2 = ft, so your answer is really
12 ft
not
144 ft


To check you know PEMDAS, make sure you agree to these:
2 * 4^2 = 32
(2*4)^2 = 64
