It is easier to understand if you draw on graph paper. Each little square represents one unit of area. So if you have a square with 4 little squares in it, then the length is 2 and the width is 2. Multiplied together it makes 4. A similar idea happens when you don't have a shape on graph paper. Instead, you use the info you are told, even if you are given a picture that doesn't look that size.
multiply length and width
to find area you multiply length times width to find volume you multiply length times width times heights
Multiply its length by its width.
multiply the length by the width to find the area
you need length and width length multiply width = area length + length + width + width = perimeter
Find the width, and multiply the length and the width.
Multiply the length and width to find the area of both a rectangle and square.
