$\huge\mathcal\red{Answer}$

The perimeter of a semicircle is half of the circle. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) or πr, where r is the radius.

$\huge\orange{ \mid{ \underbrace{ \overline{ \tt (2πr)÷2 ~ or ~ πr }} \mid}}$

$<body bgcolor = blue>\huge{\underbrace{\red{\mathit{Here, ~ r ~ is ~ the ~ measure ~ of ~ given ~ semi-circle's ~ radius ~ and ~ π=22/7 ~ or ~ 3.14}}}}$

Step-by-step explanation:

$<body bgcolor = blue>\huge{\underbrace{\red{\mathit{Perimeter ~ of ~ a ~ circle=2πr}}}}$

$<body bgcolor = blue>\huge{\underbrace{\red{\mathit{Semi-circle=1/2×circle}}}}$

$<body bgcolor = blue>\huge{\underbrace{\red{\mathit{Perimeter ~ of ~ semi-circle=1/2×2πr}}}}$

$<body bgcolor = blue>\huge{\underbrace{\red{\mathit{Answer ~ given ~ in ~ orange ~ text}}}}$
