Answer:
The answer to your question is
Total perimeter = 62.84 in
Total area = 248.52 in²
Explanation:
1.- Rectangle
Perimeter
P = 12 x 2
P = 24
Area
A = 12 x 12
A = 144 in²
2.- Triangle
Perimeter
P = 10 + 10
P = 20 in
Area
A = b x h/2
A = 12 x 8/2
A = 48 in²
3.- Semicircle
Perimeter
P = 2πr
P = 2(3.14)(6)/ 2
P = 18.84
Area
A = πr²
A = (3.14)(6)²/ 2
A = 56.52
Total perimeter = 62.84 in
Total area = 248.52 in²
