Sunday Times Teaser 2702 – Problemblem
by H Bradley and C Higgins
A small rectangular flag is composed of three rectangular areas that are coloured red, green and blue and have sides that are all integer numbers of centimetres.
The green rectangle’s area and perimeter are respectively twice and one half those of the red rectangle.
The three digits of the blue rectangle’s area are the same as the digits of the flag’s area but in reverse order.
What is the area of the flag?
