(c)   A PVC fascia gutter is 14 m long. Its temperature rises from 7oC to 24oC. Given that the coefficient
of linear expansion of PVC is 0.0000 m per oC, calculate the length in millimetres that the gutter
expands.
    Formula:
 Linear expansion =  total length x coefficient of linear expansion x
          temperature difference in oC
