Given:
Find the length of the boundary of the bat? Refer to an attached image.
Solution:
Given lengths are:
9cm, 1cm, 4cm
The bat has 2 sides of 9cm length:
=> 9cm + 9cm
=> 18 cm
The bat has 2 sides of 4cm length:
=> 4cm + 4cm
=> 8 cm
The bat has 3 sides of 1cm length: (right-side of the bat)
=> 1cm + 1cm + 1cm
=> 3 cm
According to the right-side of the bat, the bat length of the left-side is 3cm
Add all sides:
18cm + 8cm + 3cm + 3cm
=> 32 cm
Hence, the boundary of the length is 32cm
