Answer:
C
Step-by-step explanation:
Using Pythagoras' identity in right triangle BPO
with PB = 4 ( half of AB ) and OB = 5 ( radius of circle )
OP² + 4² = 5²
OP² + 16 = 25 ( subtract 16 from both sides )
OP² = 9 ( take the square root of both sides )
OP = = 3
The highest common factor is 7:
49=7*7
84=7*12
91=7*13
1/2 * 82/3 * 53/5 = 144.86 units^2
