Hey guys i found a problem in the MENSA book, i've tried to use basic algebra to this this problem but i think i'm on the wrong track.

Can anyone suggest any techniques to do this problem?

The answers are at the back of the book although i do want to know how to do it.

THE IMAGE IS ATTACHED.

This field measures 177m x 176m. It has been split up into 11 squares that exactly equal the total area. The squares are only roughly drawn to scale. All new squares are in whole yards. Can you calculate the size of each square ?

- much appreciated. (Wink)
