You divide area by length or area/length.
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.
Area of rectangle divided by its length = width of rectangle
If you do not know the length or breadth of a rectangle, you cannot know the area. If you do not know the area of a rectangle, you cannot know the length and breadth. To know the length and breadth of a rectangle, you have to know some other contributing factor in the equation. If you don't, measure it!
To find the area of your rectangle, you multiply length x width. There is no volume to a rectangle that I know of. :-)
Multiply the long side of the rectangle's length by itself.
You would also need to know the area of rectangle, along with the width in order to determine the length of the rectangle.
You take the formula for a rectangle, replace what you know, and solve for the remaining variable.
You can find the perimeter of a rectangle if you know its area and the length of one side. Divide the area by the length of the known side and the quotient will be the length of a side perpendicular to the known side, and then multiply the sum of the two sides by two to find the perimeter.
The area of rectangle is : 896.0
