Answer: 38.57

SOLUTION 1 :

AB+BC+CD+DE+EGH+HA

=5 + 3 + 5 + 8 + $\frac{1}{2}$ + 5

= 26 + $\frac{1}{2}$ ( 2 x $\frac{22}{7}$ x 4) [circumference of the circle = 2 $pi$ r]

= 26 + $\frac{1}{2}$ x 2 x $\frac{22}{7}$ x 4

= 26 + $\frac{88}{7}$

= 26 + 12.57

= 38.57cm

Answer: 30.57

SOLUTION 1 :

AB+BC+CD+DE+EGH+HA

=3 + 3 + 3 + 6 + $\frac{1}{2}$ + 3

= 18 + $\frac{1}{2}$ ( 2 x $\frac{22}{7}$ x 4) [circumference of the circle = 2 $pi$ r]

= 18 + $\frac{1}{2}$ x 2 x $\frac{22}{7}$ x 4

= 18 + $\frac{88}{7}$

= 18 + 12.57

= 30.57cm

Answer: 42.57

SOLUTION 1 :

AB+BC+CD+DE+EGH+HA

=6 + 3 + 6 + 9 + $\frac{1}{2}$ + 6

= 30 + $\frac{1}{2}$ ( 2 x $\frac{22}{7}$ x 4) [circumference of the circle = 2 $pi$ r]

= 30 + $\frac{1}{2}$ x 2 x $\frac{22}{7}$ x 4

= 30 + $\frac{88}{7}$

= 30 + 12.57

= 42.57cm

=8 + 3 + 8 + 11 + $\frac{1}{2}$ + 8

= 38 + $\frac{1}{2}$ ( 2 x $\frac{22}{7}$ x 4) [circumference of the circle = 2 $pi$ r]

= 38 + $\frac{1}{2}$ x 2 x $\frac{22}{7}$ x 4

= 38 + $\frac{88}{7}$

= 38 + 12.57

= 50.57cm

= 14 + $\frac{1}{2}$ ( 2 x $\frac{22}{7}$ x 4) [circumference of the circle = 2 $pi$ r]

= 14 + $\frac{1}{2}$ x 2 x $\frac{22}{7}$ x 4

= 14 + $\frac{88}{7}$

= 14 + 12.57

= 26.57cm
