Answer:
A. True
Step-by-step explanation:
The Triangle Inequality Theorem says that the sum of any two sides must be greater than the third side. Let's see if this is true.
a + b
9 + 1 = 10>9
a + c
9 + 9 = 18>1
c + b
9 + 1 = 10>9
the formula for perimeter is l+l+w+w
So 9+9+6+6= 30 meters of fence
I think it's the distributive property. I'm not sure. But I hope this helps.
