Ответ:
2l + 2w = a
Step-by-step explanation:
A rectangle room has 2 bases so the length and width needs to be doubled.
So, 2l + 2w = a is the right answer.
Note: I don't know if you just started the lesson but there needs to be one more dimension that needs to be recognized. This dimension is called height (h). The true equation is:
2l + 2w + 2h = a
or
2(lw + lh + wh) = a
