ABCD is a quadrilateral with BC = 8 cm. Quadrilateral AB’C&rsquo...
The quadrilateral is dilated by a scale factor of 3/4.The shape of image will be same as pre image but size will vary means it will be smaller .If Dilation factor is , means 0< Dilation factor<1, the image is be smaller than preimage.
So new length =k*original size=¾*8 = 6cm
So B’C’ = 6cm

Direction: Read the following text and answer the below questions:SCALE FACTORA 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 factorScale factor = length in image / corresponding length in objectIf 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 1:200This means that a length of 1 cm on the photograph above corresponds to a length of 200 cm 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
