The perimeter of a shape is the distance around its edge. To work out the perimeter of a hexagon multiply the length of one of its sides by 6. If its sides are 2 meters long its perimeter would be 12 meters. The area is the size of the surface. Knowing the area of a wall is important if you are planning to give it a lick of paint - otherwise how will you know how many tins of paint to buy?!
