and so ur ans will go like,

area of shaded region = area of rectangle-area of circle

Answer 2

Answer:

Area of the shaded region=Area of rectangle - Area of circle

$= area \: of \: triangle = l \times b$

$= 42 \times 42$

$= 1764cm ^{2}$

$= area \: of \: circle = r {}^{2}\pi$

$r = 14 \div 2 = 7...r = 7$

$= 22 \div 7 \times 7 \times 7$

$= 22 \times 7 = 154cm {}^{2}$

$= 1764cm {}^{2} - 154cm {}^{2}$

$= 1610cm {}^{2}$

The area of the shaded region = 1610cmsquare
