Ancient Greek Area Code breaker using multiplication and division

Using short division and short/long multiplication pupils will solve area problems of squares, rectangles, triangles and parallelograms to find out the secret message to"In battle, hoplites fought as a team. They lined up in ranks and locked their shields together with just their spears pointing over the top. Solve the area problem below to find out what this formation was called."
This includes year 5 and 6 objectives and can easily be adapted to suit learners.
It is working towards a mastery approach where different mathematical concepts are used (area, multiplication, division and problem solving).
This links to Ancient Greek topic but the code can be suited to any topic.
