You can put this solution on YOUR website!
Length, L
Width, w
Depth, h
Volume is Lwh


You know that %282w%29w%2A2=2500 from the description.
This is only a single unknown variable, so you could use the given values and information instead of using them all as variables.

w%5E2=2500%2F4
w%5E2=25%2A25
highlight%28w=25%29 and you can find L.
