Answer 1

Step-by-step explanation:

your answer is 26.28

first find the perimeter of the circle

2πr = 2×3.14×2 = 12.56

now divide it by two as we want only want the length of half of the circle so we get 6.28

now we do as usual, find the perimeter of the shaded part that is

6.28+4+8+8=26.28

Answer 2

Step-by-step explanation:

Area of rectangle

$= l \times b$

$4 \times 8$

$32cm ^{2}$

Area of semi circle

$= \frac{1}{2} \times \pi \times r {}^{2}$

$\frac{1}{2 } \times \frac{22}{7} \times 2 \times 2$

$\frac{22}{7} \times 2$

$\frac{44}{7}$

$6.29cm {}^{2} \: \: approx$

Subtract area of semi circle from area of rectangle

$= 32 - 6.29 \\ = 25.71cm {}^{2}$
