Anna Mc Sherry from St Crispin's School and Oliver Hayward from
Little Aston Primary School worked out that the string was fixed to
the corner of the shed. 
<p>Oliver reasoned as follows:<br />
" The rope is tied to the top left hand corner of the shed.<br />
I know this because the top of the shed is 3m and the side of the
shed is 2m, and if it starts at the end of the 3m side and the rope
is 4m long it will stretch over all of the top edge and half way
down the 2m edge: 3m + (2 divide by 2) = 4m.<br />
The second piece of evidence is that if the rope is tied to the top
of the 2m edge and ends up 2/3 of the way across, it means that the
rope will have stretched down the 2m edge and 2/3 of the way across
the 3m bottom edge, meaning it will have stretched 4m, and that's
how long the rope is."</p>
<p>Krupali Lakhani, Katie Phillips and Ginny Horten-Middleton from
North London Collegiate School went on to work out the area of
George's shape:<br />
" We found 3/4 of the area of a circle of radius 4. We added this
to the area of a 1/4 of a circle with the radius two and the area
of a quarter of a circle with radius 1. All together this gave us
13.25

<p>No one suggested that the area could be increased by fixing the
string to a different point on the shed.</p>
<p>Well done to you all.</p>
