If the width of a rectangular field is 17 kilometers and the field has an area of 578 square kilometers what is the length of the field

Question

In this problem, the knowns are 
Width = W = 17
Area = A = 578

the unknown is 
Length = L = x


Now we move onto the formula 

area of rectangle = length times width

which is the same as 

A = L*W

then plug in the knowns and solve for the unknown

578 = x*17

x = ???

I'll let you do the rest
