Answer:
6ab
Step-by-step explanation:
3 x a x 2 x b
= 3 x 2 x a x b ( because multiplication is commutative, which basically means you can move the numbers and variables anywhere in the expression).
= 6ab ( we leave out the multiplication signs. They are understood.)

Answer: 48g
Step-by-step explanation:
All you are doing is multiplying the number of game markers, forty-eight times, so you can write your answer as, 48g.
The arc length is a quarter of the circumference of the full circle, so 2πr/4.
The straight sides are both radii, so each length r.
Total perimeter
p = 2πr/4 + r + r = r(π/2 + 2)
We put in r=2, π=3.14 and get
p = (2(3.14/2 + 2)) = 3.14 + 4 = 7.14
Answer: 7.14 km
