An algorithm to calculate area of room in rectangular shape is given below. However, there are errors in the algorithm. If there is$/$are error$($s$)$ in the algorithm, explain them. Also rewrite the correct algorithm.

$\backslash$table$[[1,$Set length to $0],[2,$Calculate area using formula: area $=$ width $$ length$],[3,$Display "What is the room's width?"$],[4,$Input width$],[5,$Set width to $0],[6,$Display "What is the room's length?"$],[7,$Input length$],[8,$Display area$]]$
