Find the perimeters of the given figures.

Answer

To find the perimeters of the given figures, we will follow these steps:

### Step 1: Identify the sides of Figure A
- We will list the lengths of all the sides of Figure A.
- From the video, the sides are: 1 cm, 3 cm, 2 cm, 3 cm, 4 cm, 1 cm, 3 cm, 2 cm, 3 cm, 4 cm, 1 cm, 3 cm, 2 cm, 3 cm, 4 cm.

### Step 2: Sum the lengths of the sides of Figure A
- We will add all the side lengths together:
- 1 + 3 + 2 + 3 + 4 + 1 + 3 + 2 + 3 + 4 + 1 + 3 + 2 + 3 + 4
- Performing the addition step by step:
- 1 + 3 = 4
- 4 + 2 = 6
- 6 + 3 = 9
- 9 + 4 = 13
- 13 + 1 = 14
- 14 + 3 = 17
- 17 + 2 = 19
- 19 + 3 = 22
- 22 + 4 = 26
- 26 + 1 = 27
- 27 + 3 = 30
- 30 + 2 = 32
- 32 + 3 = 35
- 35 + 4 = 39
- 39 + 1 = 40
- 40 + 3 = 43
- 43 + 2 = 45
- 45 + 3 = 48
- 48 + 4 = 52

### Step 3: State the perimeter of Figure A
- The perimeter of Figure A is 52 cm.

### Step 4: Identify the sides of Figure B
- Now, we will list the lengths of all the sides of Figure B.
- The sides are: 1 cm, 4 cm, 0.5 cm, 2.5 cm, 0.5 cm, 2.5 cm, 0.5 cm, 4 cm.

### Step 5: Sum the lengths of the sides of Figure B
- We will add all the side lengths together:
- 1 + 4 + 0.5 + 2.5 + 0.5 + 2.5 + 0.5 + 4
- Performing the addition step by step:
- 1 + 4 = 5
- 0.5 + 0.5 = 1 (adding the two 0.5s)
- 5 + 1 = 6
- 6 + 4 = 10
- 2.5 + 2.5 = 5 (adding the two 2.5s)
- 10 + 5 = 15

### Step 6: State the perimeter of Figure B
- The perimeter of Figure B is 15 cm.

### Final Answer:
- The perimeter of Figure A is 52 cm.
- The perimeter of Figure B is 15 cm.
