Let n be the common factor for the ratio 6:5. Then:
6n+5n=330
11n=330
n=30
aerobics=6n=180 min
weight training=5n=150 min

Parallelogram:
just multiply 16 by 30.
The area is 480.
Semicircles:
Since there are 2 semicircles, they can be merged to one circle.
The area of a circle is πr²
The diameter is 28, so the radius is 14.
Substitute and solve.
π14²
π196 ≈ 615.8
Now add 615.8 with 480
Your answer is 1,095.8 units squared.
1 mile has 3 markers.
2 miles have 6 markers.

Hope this helps!
