[quote=Anonymous]She does not understand because the key to the question is illegible. This is how you explain perimeter: Perimeter is when you trace the line on the outside of the figure. If you colored in each block that would be the AREA. We are not looking for AREA, we are looking for PERIMETER. Each side of the block is 1 unit but we only count the sides that are facing outward. So trace, with your pencil around the shaded part. Each time you move from one block to the next or at each corner of a block you count ONE (1). So you trace around the shaded area counting each time you hit a corner. The answer is 24. They give you the jacked up picture of a cube and say it is 1 unit to try to trick you into giving the area. If you count the blocks it is 18 blocks, the area is 18... BUT the Perimeter is 24. [/quote]
