**1.** The first picture, from which we start,
is as we said already one of
a child sitting in front of the school, with a cat on her lap. It is
drawn on a scale of 1 to 10. This means that a centimeter on the drawing
is in reality 10 centimeters. A centimeter (abbreviated "cm.") is the
hundredth part of a meter, which corresponds to the yard as a unit of
length. To be precise, a meter is 3.37 inches longer than 1 yard. One
centimeter is therefore nearly 0.4 inch. In both length and height, the
picture measures 15 centimeters, or nearly 6 inches. An arrow shows the
direction of north.

1 cm. in picture = 10cm. in actuality.

Scale of picture therefore = 1:10
