The two triangles with the given perimeter is attached .
Perimeter is the sum of all sides.
For the first triangle , sies are 2a,2a and b.
So the perimeter is
For the second triangle, sides are a,a, and 2a+b. Therefore perimeter is
So for both triangles, perimeter is
The commutative property of addition means the order of the addends doesn't matter; we get the same sum. In symbols
<span>11 + 7 = 7 + 11, choice B, is a good illustration of commutativity.
The next part asks us to use the commutative property. Looking at the choices, we see it's not the commutative property of addition we're to use, it's the commutative property of multiplication. Let's write that generally first:
</span>
Applying that, <span>(4 + 7) * 3 = 3*(4+7), again choice B.
</span>
