Answer 1

Answer:

1. area of triangle=1/2x4x3=6sq.cm
2. area of semi circle=π4²/2=3.14x8=25.12
3. required area of the figure=6+25.12=31.12sq cm

Answer 2

74.28 cm^2

Step-by-step explanation:

area of the following figure ,

= area of triangle + area of semi-circle

= 1/2 × b × h + 1/2 πr^2

$= \frac{1}{2} ( 8 \times 6 + \frac{22}{7} \times 4 \times 4)$

=1/2(48 + 50.28)

= 98.28/2

= 74.28 cm^2
