A plan of an area drawn with the original scale of 1 cm = 10 m, has shrunk such that a line, originally 15 cm long on the plan, measures now 14.5 cm. The shrunk scale is given by 1 cm equal to A. 0.97 m B. 9.70 m C. 10.34 m D. 10.97 m Shrunk scale=original scale * shrinkage factor. Shrinkage factor=Shrunk length/actual length. =0.145𝑚/0.15𝑚. =0.9667 Shrunk scale = 0.9667*1/10=0.09667 = 1/0.09667 = 10.34m = 10.34m.
