Because it is only true for rectangles, not any other shape.
12X12 12X12
volume is defined as distance cubed, or length times width times height
length times width length times width
Area
its length times width
length times width equals the area of a rectangle. length times width equals the area of a rectangle. area
multiply length times height times width
Area = (length) times (width)Length = (area) divided by (width)Width = (area) divided by (length)
Chile has a length of about 4300 km and a width of about 180 km, which means its length is about 24 times its width.
Length width dept
It is the area of the rectangle which is length times width
perimeter 24 so length + width half of that ie 12. Length 3 times width must be 9 and width 3.
