Answer:

The length of the floor is
(15x^(2)+4x)\ ft

Explanation:

we know that

The area of a rectangle ( classroom floor) is equal to


A=LW

in this problem we have


A=(30x^(3)+8x^(2))\ ft^(2)


W=2x\ ft

substitute in the formula and solve for L


(30x^(3)+8x^(2))=2x(L)

Divide by 2x both sides


L=(15x^(2)+4x)\ ft
