A rectangle has a length, a width, and an area. If you know any two of them, you can figure out the missing one.

the length of a rectangle is 8 more than the width. the area os 345 centimeters. find the length and width of the rectangle

Area of rectangle divided by its length = width of rectangle

You cannot find the area of a rectangle if you only know its length. You need to know its width too. Then you multiply its length by its width.
