Explanation:
We are given rectangles made of 1 cm × 1 cm squares.
-
Area = number of squares inside the rectangle (in square cm).
-
Perimeter = total length around the outside (in cm). For a rectangle, perimeter = 2 × (length + width), where length and width are in cm (i.e., number of squares along each side).
Let’s go one by one:
1) Rectangle is 5 squares wide and 2 squares tall.
- Area = 5 × 2 =
10 square cm
- Perimeter: length = 5 cm, width = 2 cm → 2 × (5 + 2) = 2 × 7 =
14 cm
2) Rectangle is 6 squares wide and 1 square tall.
- Area = 6 × 1 =
6 square cm
- Perimeter = 2 × (6 + 1) = 2 × 7 =
14 cm
3) Rectangle is 4 squares wide and 3 squares tall.
- Area = 4 × 3 =
12 square cm
- Perimeter = 2 × (4 + 3) = 2 × 7 =
14 cm
4) Rectangle is 6 squares wide and 3 squares tall.
- Area = 6 × 3 =
18 square cm
- Perimeter = 2 × (6 + 3) = 2 × 9 =
18 cm
5) Rectangle is 5 squares wide and 2 squares tall (same as #1, just drawn differently).
- Area = 5 × 2 =
10 square cm
- Perimeter = 2 × (5 + 2) =
14 cm
6) Rectangle is 7 squares wide and 2 squares tall.
- Area = 7 × 2 =
14 square cm
- Perimeter = 2 × (7 + 2) = 2 × 9 =
18 cm
Let me double-check all:
1) 5×2=10, P=2(5+2)=14
✔
2) 6×1=6, P=2(6+1)=14
✔
3) 4×3=12, P=2(4+3)=14
✔
4) 6×3=18, P=2(6+3)=18
✔
5) 5×2=10, P=14
✔
6) 7×2=14, P=2(7+2)=18
✔
All correct.
Final Answer:
1) Area = 10 square cm, Perimeter = 14 cm
2) Area = 6 square cm, Perimeter = 14 cm
3) Area = 12 square cm, Perimeter = 14 cm
4) Area = 18 square cm, Perimeter = 18 cm
5) Area = 10 square cm, Perimeter = 14 cm
6) Area = 14 square cm, Perimeter = 18 cm
