You are given Lisa's own large warehouse that is 8,100 square feet and because Isabel wanted to sell books, Lisa allowed about 100 square feet or up to her whole warehouse. Her only requirement is that all spaces must be square. If the the total length of each row of bookshelves will be of the length of the storage space and let x be the area of the space that Isabel rents and f(x) represent the total length of a row of bookshelves. You are asked to find the length of a row of bookshelves.
The area of the square is x = s² where x represents the area of the square and s is the length of one side.
Le us say that Isabel will use the entire warehouse, then
8,100 square feet = s²
√8, 100 square feet = √s²
s = 900 feet
