Step-by-step explanation:
diameter = 14cm
radius = 7cm
area of the square =
(14 × 14 )cm = 196cm²
area of 1st semicircle = πr²× 1/2
= ( 22/7 × 7²) 1/2 cm²
= 77cm²
area of 2nd semicircle = πr² × 1/2
= ( 22/7 × 7² ) 1/2 cm²
= 77cm²
area of shaded region = (196 - 154) cm²
= 42cm².

given, d = 14cm
so, r = 7cm
area of the square=(side)²
=(14 × 14 )cm
=196cm²
area of 1st semicircle = area of 2nd semicircle = πr²/2
= ( 22/7 × 7²)/2 cm²
= 77cm²
area of shaded region = (196 - 154) cm²
= 42cm².
