Yes it is correct.

Answer 3

But you didn't have to do the a^2 because you could have used the area of each square.

if you are trying to determine the areas .... let the area of one little square be defined as:

4a = 5, then a = 5/4

there are 9 little a's in the bottom one

Answer 6

Daniel,sou de Goiânia. Quanto a área, foi isso mesmo que fiz.
