The scale sketch represents a barn $ABCD$. Here, $AB = 7\text{ m}$ and $BC = 4\text{ m}$. The scale used is $1\text{ cm}$ to represent $1\text{ m}$. A horizontal rail is fixed to the outside wall of the barn from $A$ to $B$. Jasper is a dog on a $3\text{ m}$ rope. One end of the rope is fastened to the rail, and that end may move along the rail.
