Step-by-step explanation:

the perimeter of a polygon is equal to the sum of the sides of polygon

so

  the perimeter of parallelogram=21+15+21+15=72m

   the perimeter of triangle =10+14+16+40m

Answer 2

1. a) 2(l+b) = 2(16+10) = 2 x 26 = 52cm

b) 2(l+b) = 2(21+15) = 2 x 36 = 72cm

c) sum of all sides = 10+14+16 = 40cm
