Step-by-step explanation:
We know that area of Trapezium =

1/2 * (16+48) * 20
= 640 m²
Now, for semicircle,
1/2 * pi * r²
= 1/2 * 3.14 * 18.86 * 18.86
= 558.44 m²
Adding both,
1198.44 m² ~ 2000 m²
Hope it helps :)
Answer:
See below.
Step-by-step explanation:
The train leaves station A at 13:44 and arrives at station B at 15:12.
Which means the train took 1 hour and 28 minutes to arrive at station B.
The train travels at 300 km/h. It took at least one hour, so the answer > 300 km.
Now, the remaining 28 minutes. We divide them by 60, as there’s 60 minutes in one hour and multiply by 300, as that’s how fast the train travels per hour.
28/60*300 = 140.
300 + 140 = 440.
The distance between the stations is 440 km.
