diameter of the semi circle =7
radius= 7/2
perimeter semi circle = 2πr/2
=22/7×2×7/2/×1/2=11
perimeter of rectangle= 2×( 10.5+4) =29
perimeter of shaded region = 29+11=40
radius= 7/2
perimeter semi circle = 2πr/2
=22/7×2×7/2/×1/2=11
perimeter of rectangle= 2×( 10.5+4) =29
perimeter of shaded region = 29+11=40

i m sorry for giving wrong ans it should be 40-7 as in πr we will get the area of the diameter also thus we have to subtract 7(as it is diameter ) and we will get 33 as the ans
