Lady Belinda is an enthusiastic gardener.
One of her gardens is oblong in shape, enclosed by
a high holly hedge, and she is turning it into a rosary for the
cultivation of some
of her choicest roses.
She wants to devote exactly half of the area of the garden to the
flowers, in one large bed, and the other half to be a path going all
round it of equal breadth throughout.
Such a garden is shown in the
diagram at the foot of the picture.
How is she to mark out the garden under these
She has only a tape, the length of the garden, to
do it with, and, as the holly hedge is so thick and dense, she must
make all her measurements inside.
