Maths - Area of Composite Shapes

Check out this fantastic Maths work done by our very own, Dorothy Chang! She has created a composite shape, then clearly shown how she has divided the shape into triangles and rectangles in order to calculate the total area of the shape. Great work, Dorothy! You are a star.

Can anyone solve this?

Good Afternoon Room 1,

I noticed Briar has shared a maths problem for translation of a triangle. Have a look at her blog to see the post. Can you solve it? If so, leave a comment on her blog post!

Thanks,
Miss Hudson
