Area and Perimeter of Rectangles 1 math worksheet with six grid-based rectangle problems for calculating area and perimeter.

Let’s solve each rectangle one by one. Remember:

- Area = number of squares inside → count the rows × columns
- Perimeter = distance around the outside → add up all 4 sides (top + bottom + left + right)

Each square is 1 cm, so we can just count the units.

Problem 1:

Rectangle has 2 rows and 5 columns.

→ Area = 2 × 5 = 10 square cm

→ Perimeter: top = 5, bottom = 5, left = 2, right = 2 → 5+5+2+2 = 14 cm

---

Problem 2:

Rectangle has 1 row and 6 columns.

→ Area = 1 × 6 = 6 square cm

→ Perimeter: top = 6, bottom = 6, left = 1, right = 1 → 6+6+1+1 = 14 cm

---

Problem 3:

Rectangle has 4 rows and 4 columns.

→ Area = 4 × 4 = 16 square cm

→ Perimeter: top = 4, bottom = 4, left = 4, right = 4 → 4+4+4+4 = 16 cm

---

Problem 4:

Rectangle has 3 rows and 7 columns.

→ Area = 3 × 7 = 21 square cm

→ Perimeter: top = 7, bottom = 7, left = 3, right = 3 → 7+7+3+3 = 20 cm

---

Problem 5:

Rectangle has 3 rows and 6 columns.

→ Area = 3 × 6 = 18 square cm

→ Perimeter: top = 6, bottom = 6, left = 3, right = 3 → 6+6+3+3 = 18 cm

---

Problem 6:

Rectangle has 2 rows and 8 columns.

→ Area = 2 × 8 = 16 square cm

→ Perimeter: top = 8, bottom = 8, left = 2, right = 2 → 8+8+2+2 = 20 cm

---

Final Answer:

1) Area = 10 square cm, Perimeter = 14 cm
2) Area = 6 square cm, Perimeter = 14 cm
3) Area = 16 square cm, Perimeter = 16 cm
4) Area = 21 square cm, Perimeter = 20 cm
5) Area = 18 square cm, Perimeter = 18 cm
6) Area = 16 square cm, Perimeter = 20 cm
