For figure

d = 16 cm

r = 8 cm

l = 16 cm

b = 3 cm

Area of figure = 2× area of semicircle + area of rectangle

= 2 × π r²/ 2 + l × b

= π r² + l × b

= π × 8 × 8 + 16 × 3

= 64 π + 48

= 201.06193 + 48

= 249.06193 cm²

Perimeter of figure = 2 × ( πr + d) + 2 ( l + b )

= 2 × ( π × 8 + 16 ) + 2 ( 16 + 3 )

= 16 π + 32 + 2 × 19

= 50.26 + 32 + 38

= 120.26 cm

Perimeter of given figure is 120.26 cm .


HOPE IT IS MOST HELPFUL!!!!!!!!!!!!
