Question from anonomous, a student:

I need to fit 7 different rectangles on grid paper of 1cm squared.
Each squared centimeter equals 4 squared metres, and it needs to end up as area 64 square metres.

If you want 1cm² = 4m² consider the following arrangement:

table

The large rectangle is 8m x 2m and each of the small rectangles are 4m x 2m. This would require you to have widths that are 0.5cm for each rectangle, a length of 2 cm for the large rectangle and lengths of 1cm for each of the small rectangles.
