Step-by-step explanation:

here's the solution :-

1st question :

the given figure has a triangle and a semi - circle, so area

in the triangle,

base = 3 cm

height = 4 cm

so, area of triangle

=》

\frac{1}{2}  \times 3 \times 4

=》

6 \: cm {}^{2}

about the semi - circle, radius = 4 / 2 = 2 cm

so, area =

\frac{1}{2} \pi r {}^{2}

=》

\frac{1}{2} \times  3.14 \times 2 \times 2

=》

6.28

area of circle = 6.28 sq.cm

=》 area of triangle + area of semi - circle

=》6 + 6.28 = 12.28 sq.cm

2nd question :-

the given figure is a rectangle with a semi - circle

so, about the rectangle

length = 12 inwidth = 6 in

area =

length \:  \times  \: width

=》

12 \times 6

=》

72 \: in {}^{2}

about the semi - circle,

radius = 6 / 2 = 3 in

area =

\frac{1}{2} \pi \:  {r}^{2}

=》

\frac{1}{2}  \times 3.14 \times 3 \times 3

=》

14.13\: in {}^{2}

area of the figure =

=》area of rectangle + area of semi- circle

=》72 + 14.13

=》86.13 sq.in
