Answer 1

The official dimensions of the rectangular flag are: ratio of length to width is 3:2; the centre of the circle is the point of intersection of the diagonals of the rectangle and its diameter is 3/5 the width of the flag.

If 2x is the width, 3x is the length and the circle’s diameter is 6x/5.

1cm=2m for scaling.

6x/5=10m on the flag so x=50/6=25/3m. The dimensions of the actual flag are 25m by 50/3m.

On the scale version, these are 12.5cm and 25/3cm.
