For this case we have that the conversion from feet to meters is given by:

1m = 3.28feet

Then, converting the specified measure we have:

$2.1m ^ 2 (\frac {3.28feet} {1m}) ^ 2$

Rewriting we have:

$2.1m ^ 2 (\frac {3.28feet} {1m}) ^ 2 = 22.6feet ^ 2$

Answer:

the student’s error is: He forgot to square

the correct area in square feet is 22.6feet².
