Let’s look at a square block that represents [b]1 square unit of area[/b]. Each side of the square is [b]1 unit[/b] long.[br][br]To find the [b]perimeter[/b], we add all the sides:[br][br][b]1 + 1 + 1 + 1 = 4 units[/b][br]So, the perimeter is [b]4 units[/b], and the area is [b]1 square unit[/b].[br]Even though both are about size, [b]area and perimeter measure different things[/b]. One is about [b]covering[/b], the other is about [b]surrounding[/b].
