Answer 2

$\huge\bf\underline{\underline{ Given:-}}$

ABCD is a square and sides are bounded by four semicircular region.Each side of square is 21 cm.

$\huge\sf\underline{\underline{To \: Find:-}}$

• perimeter of figure

$\huge\sf\underline{\underline{Formulas \: Used:-}}$

$\boxed{\bf \: perimeter \: of \: semicircle = \frac{πd}{2} }$

$\huge\sf\underline{\underline{ Answer :-}}$

Side of square = 21 cm

diameter of semicircle = 21 cm

Perimeter of one semicircle = $\frac{π × 21}{2 }$

perimeter of 4 figures = $\frac{4 × π × 21}{ 2}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 131.88 cm$
