Answer:
a) 183/12 cm and b) 27 cm
Step-by-step explanation:
For a)
Perimeter = Sum of all the sides.
so,
Perimeter = AB + BC + AC
Perimeter = 17/3 + 21/4 + 13/3
Perimeter = 68+63+52/ 12
Perimeter = 183/ 12 cm
You can convert it in Decimals too.
For b)
Perimeter = 3/2+ 45/4+ 9/4 + 3/2 + 3/4+ 39/4
Perimeter = 6+45+9+6+3+39/4
Perimeter = 108/4
Perimeter = 27 cm.

(B)
AB=9.75
BC=0.75
CD=1.5
DE=2.25
EF=11.25
AF=1.5
Perimeter=sum of all sides
9.75+0.75+1.5+2.25+11.25+1.5=27
