Answer 1

Answer:

Perimeter=46.28 cm Area=84.56cm^2

Step-by-step explanation:

Perimeter of figure=p(recatangle)-4+p(semi circle)

=2(18+4) - 4 + π*2

=2*22 - 4 + 3.14*2

=44 - 4 + 6.28

=40 + 6.28

=46.28 cm

Area of fig.= ar(rectangle) +ar(s.c.)

= 18*4 + π*2*2

= 72 + 3.14*4

=72 + 12.56

= 84.56 cm^2
