last week we did 3D shapes and 2D shapes but know we are doing perimeter what we had to did is that we had to do 5 shapes in our maths book and we had to see how many sides then we had to say like 3 sides and 13 side so we had to do 3+3+13+13= is 32 then we had to times it like 3x13= is 39 so after we did does 5 shapes we had to do the same thing.
