The first field is a very odd shape; none of the four sides are the same length, but they are all an exact number of metres long. The other odd thing is that two of the opposite corners are exact right angles.
This field is as small as it can be within these constraints - so what is its area? And by implication, how long are the four sides?
When you have worked out the size of the first field, we can consider the second field. It too has four sides, none of which are the same length, but all an exact number of metres long. Also, it too has two opposite corners that are exactly 90 degrees.
And to finish off the peculiarities, its area is precisely twice that of the first field.
So how long are the four sides of the second field?
