Geometry Area Perimeter Volume

Geometry Starter questions – lets get those grey cells working! What is the area and perimeter of these shapes: 5cm 7cm6c m 5cm

Geometry Now lets get down to business. What if we did not know the actual dimensions of these shapes. How would you explain the area and perimeter x cm y cmz cmx cm z cm

Geometry Area of the shapes can be expressed as: x cm y cm x cm = x times y Square = x times x = x 2 = xy Rectangle

Geometry z cm Triangle Then what about this shape? Or this? = z times z? or perhaps z times z times z?

Geometry Investigation into the area and perimeter of regular and irregular polygons By the end of todays lesson you will have: Worked out how to calculate the area and perimeter of a range of different polygons Expressed this in terms of x, y and z
