Question

m3|l1 how well can you measure?

square | side length (cm) | perimeter (cm)
a | 5 |
b | 3.5 |
c | 6 |
d | 2.2 |

Explanation:

Step1: Recall perimeter formula for square

The perimeter \( P \) of a square is given by \( P = 4 \times \text{side length} \), since a square has 4 equal sides.

Step2: Calculate perimeter for Square A

Side length of Square A is \( 5 \) cm. Using the formula:
\( P_A = 4 \times 5 = 20 \) cm.

Step3: Calculate perimeter for Square B

Side length of Square B is \( 3.5 \) cm.
\( P_B = 4 \times 3.5 = 14 \) cm.

Step4: Calculate perimeter for Square C

Side length of Square C is \( 6 \) cm.
\( P_C = 4 \times 6 = 24 \) cm.

Step5: Calculate perimeter for Square D

Side length of Square D is \( 2.2 \) cm.
\( P_D = 4 \times 2.2 = 8.8 \) cm.

Answer:

• Square A Perimeter: \( 20 \) cm
• Square B Perimeter: \( 14 \) cm
• Square C Perimeter: \( 24 \) cm
• Square D Perimeter: \( 8.8 \) cm

(If filling the table, the perimeters are \( 20 \), \( 14 \), \( 24 \), \( 8.8 \) for A, B, C, D respectively.)
