Todays activity is going to test you on both area and perimeter of the shapes.
Area - The space taken up by an object. Find rectangles and use the formula: Length X Width. Alternatively, you can work out the area of 1 square and multiply this by the number of squares in the shape.
Perimeter - The distance around the outside of the shape. Add the lengths of each side of the shape to find its perimeter. Alternatively, You can count the squares number of squares you cross as you work you way all the way around the shape (once you have checked the key to find out the unit of measure for 1 square).
