It is a combination of a rectangle & a semicircle.
we know,
perimeter of rectangle = 2(l + b)
= 2×(2 + 4)
=12.
perimeter of semicircle = π r
=π × 1
=π cm
Total perimeter = 12 +π= 12+ 3.14 = 15.14cm
We have to subtract 2 CM as it is included in semicircle & rectangle.
Hence the answer is = 15.14- 2 = 13.14 cm
Thanks for a2a & for free points

This answer is wrong
In book 13.14 cm is given
Then subtract 2 CM as some length is Included in both semicircle & rectangle
I didnt see that
My answer was for combining the individual perimeters
Ok
