we know that
[the area of semicircle]=pi*r²/2
for r=3.5 units
[the area of semicircle]=pi*3.5²/2---> 19.24 units²
[the area of the triangle]=b*h/2
b=7 units
h=3 units
[the area of the triangle]=7*3/2-----> 10.5 units²
the area of the figure=19.24+10.50----> 29.74 units²----> 29.7 units ²
the answer is
29.7 units ²
