Answer: The answer is C) 44 units.

Step-by-step explanation:

The question is asking for perimeter, not area. Instead of multiplying 9*13 to get area, we need to add the sides together. If the width on one side is 13, so is the witdh on the other side. This rule applies to the length as well.

9 + 9 + 13 + 13 = 44, so the perimieter of the rectangle is 44 units.

This is my last question by the way

Part A:

There are 25 blocks for the length, and the length of each is 5.5 inches. 5.5x25=137.5

There are 9 blocks for the height, and each is 2.75 inches. 2.75x9=24.75

Since we're trying to find how much longer the length is to the width, we find the difference. 137.5-24.75=112.75

So part A answer is 112.75 (or 112¾)

Part B:

We know the length is 137.5 and the height is 24.75. To find how many times longer the length is, we need to divide to see how many 24.75 can go into 137.5.

137.5÷24.75=5.55

So the answer to part B is 5.55. Given the context, the answer would probably be 5, because that's how many entire height can fit.

Sorry if it's wrong lol
