Answer 1

8) a regular dodecagon has 12 equal sides.  So if one side is 9.25 cm, a formula we can use is:
P = 12*9.25, which is:
P = 111 cm

9) A rhombus has four equal sides, so a formula we can use is:
P = 4*1.75, which is:
P = 7 yd

10) A paralleogram has four sides where opposite sides are equal, so a formula we can use is:
P = 2*10.4 + 2*5.6, which is:
P = 32 m
