Question 52319
Assuming the object your talking about is a rectangle...

let l = length
let w = width

{{{l*w=18.75}}}

But of course, we can have an infinite amount of either length or width.
1*18.75 will work, also 2*9.375 or 4*4.6875... Actually we have so many possiblites that it will require a graph to tell us 

Using a graphing caluculator, type {{{Y=(18.75/x)}}}, The graph tells us of all the possible answers
