How can you find the area of a square and rectangle

The area of a square can be found by knowing the length of one side. Once you know the length of one side, you plug it into this formula:

Area of a square = side × side = side²

The area of a rectangle can be found by knowing the length and width of the rectangle. Once you know that, you plug it into this formula:

Area of a rectangle = length × width
