It is true that 1 foot = 12 inches. explain why it is not true that 1 square foot = 12 square inches.
NikAS [45]

we know that

1 foot=12inch

Since, we have to find 1 foot^2

so, we will take square both sides

(1 foot)^2=(12inch)^2

(1)^2 foot^2=(12)^2inch^2

1 foot^2=144 inch^2

so, we can see that it is not equal to 12 inch^2

that's why 1 foot^2=12 inch^2 is not true
