Question 18
Rectangles $ABCD$ and $MNPQ$ are each divided into two rectangles, numbered 1,2 and 3,4 as shown. The area of rectangle 2 is four times that of rectangle 1, and its perimeter is twice that of rectangle 1. The same relations hold for rectangle 4 compared with rectangle 3. Given $AD=MN$, find $4AB/MQ$.
