Question 7
Each diagram is a 15 by 6 board with 2018 shaded. Every square is 1 cm by 1 cm. A long diagonal joins opposite square vertices; a short diagonal joins midpoints of adjacent sides. Find the total shaded area, in square centimetres. The sources print two slightly different versions of digit 1. Both are retained as A and B; give the shaded area for each version, in that order. Enter A,B separated by a comma.
