1. Step-by-step explanation:

   Perimeter of Triangle =32cm

   two sides are =8 CM and 11cm

   let found the third side:-

   perimeter of triangle = a+b+c

   32=8+11+c. = c=32-19=13cm

   Herones formulae =√s(s-a) (s-b) (s-c)

   s=a+b+c/2

   8+11+13/2

   =32/2

   =16

   Area of triangle =√16(16-8)(16-11)(16-13)

   =√16*8*5*3

   [tex]16 \times 8 \times 5 \times 3 \\ = [/tex]

   √1920

   =43.82square cm
