Answer:
B and D (
Step-by-step explanation:
1*2/3*2=2/6
1*3/3*3=3/9
Answer: P = 2716.3448786 or about 2700
∠2 = 41°
∠2 + 49° + 90° = 180°
∠2 + 139° = 180°
∠2 = 180° - 139°
total area = 217 m³
area of the triangle
= 14 × 10
= 140 m²
area of a semicircle
= 1/2 × 22/7 × 7 × 7
= 77 m²
total area
= 140 + 77
= 217 m³
