Step-by-step explanation:
the perimeter is the sum of the 4 individual sides.
if the sides are doubled, so is the sum of them.
therefore, the new perimeter is then
12×2 = 24 cm
You divide 134 by 8 and the answer would be how many classes. The answer is 16.75, I would think anyways.
1. 6 : 13
2. 2 : 13
3. 5 : 13
4. 13 : 6
5. 11 : 13
6. 5 : 12
7. 4 : 12
8. 12 : 4
Hope this helps.
