A scale drawing of an object is the same shape at the object but a different size. The scale of a drawing is a comparison of the length used on a drawing to the length it represents. The scale is written as a ratio. The ratio of two corresponding sides in similar figures is called the scale factor Scale factor= length in image / corresponding length in object If one shape can become another using revising, then the shapes are similar. Hence, two shapes are similar when one can become the other after a resize, flip, slide or turn. In the photograph below showing the side view of a train engine. Scale factor is 1:200 This means that a length of 1 cm on the photograph above corresponds to a length of 200cm or 2 m, of the actual engine. The scale can also be written as the ratio of two lengths.The length of AB in the given figure:

Answer: a
Explanation:The height of the
equilateral triangle ABC divides
the base into two equal parts at
point D.
Therefore,
BD=DC= 2.5cm
In triangle ABD, using Pythagoras
theorem,
AB2=AD2+BD2
52=AD2+2.52
AD2 = 25-6.25
AD2=18.75
AD=4.33 cm
