Let’s solve each problem one by one. We’ll find the
area and
perimeter for each square.
Remember:
- For a
square, all sides are equal.
-
Area = side × side (or side²)
-
Perimeter = side + side + side + side (or 4 × side)
---
Problem 1: Side = 5 cm
Area = 5 × 5 =
25 cm²
Perimeter = 4 × 5 =
20 cm
---
Problem 2: Side = 11 yd
Area = 11 × 11 =
121 yd²
Perimeter = 4 × 11 =
44 yd
---
Problem 3: Side = 15 in
Area = 15 × 15 =
225 in²
Perimeter = 4 × 15 =
60 in
---
Problem 4: Side = 10 m
Area = 10 × 10 =
100 m²
Perimeter = 4 × 10 =
40 m
---
Problem 5: Side = 3 ft
Area = 3 × 3 =
9 ft²
Perimeter = 4 × 3 =
12 ft
---
Problem 6: Side = 9 mm
Area = 9 × 9 =
81 mm²
Perimeter = 4 × 9 =
36 mm
---
Problem 7: Side = 4 yd
Area = 4 × 4 =
16 yd²
Perimeter = 4 × 4 =
16 yd
---
Problem 8: Side = 7 m
Area = 7 × 7 =
49 m²
Perimeter = 4 × 7 =
28 m
---
Problem 9: Side = 12 in
Area = 12 × 12 =
144 in²
Perimeter = 4 × 12 =
48 in
---
Final Answer:
1) Area: 25 cm², Perimeter: 20 cm
2) Area: 121 yd², Perimeter: 44 yd
3) Area: 225 in², Perimeter: 60 in
4) Area: 100 m², Perimeter: 40 m
5) Area: 9 ft², Perimeter: 12 ft
6) Area: 81 mm², Perimeter: 36 mm
7) Area: 16 yd², Perimeter: 16 yd
8) Area: 49 m², Perimeter: 28 m
9) Area: 144 in², Perimeter: 48 in
