To find the perimeter of a square, you add up the lengths of all four sides. Since a square has four equal sides, you can also multiply the length of one side by 4.
Formula: Perimeter = Side × 4
Let's solve for each square:
1.
First Square (Side = 5 cm):
* Calculation: $5 \times 4 = 20$
* Perimeter = 20 cm
2.
Second Square (Side = 4 cm):
* Calculation: $4 \times 4 = 16$
* Perimeter = 16 cm
3.
Third Square (Side = 7 cm):
* Calculation: $7 \times 4 = 28$
* Perimeter = 28 cm
4.
Fourth Square (Side = 3 cm):
* The worksheet asks for "Perimeter Area". This is likely a typo and just means "Perimeter", as area would be measured in square centimeters ($cm^2$) and calculated differently ($side \times side$). Given the context of the other questions, we will calculate the perimeter.
* Calculation: $3 \times 4 = 12$
* Perimeter = 12 cm
Final Answer:
- For the 5cm square: Perimeter =
20 cm
- For the 4cm square: Perimeter =
16 cm
- For the 7cm square: Perimeter =
28 cm
- For the 3cm square: Perimeter =
12 cm
