Of course! Let's solve each problem step by step. The goal is to find the
area of each rectangle.
---
📌 Key Concept:
The
area of a rectangle is calculated using the formula:
>
Area = Length × Width
If the rectangle is made up of small squares (like in problems 1–4), you can also count the total number of squares — since each square represents
1 square cm, the total count equals the area in square cm.

## 🔢 Problem-by-Problem Solution:
---
1)
This rectangle is made of a grid.
- It has
5 columns (width) and
4 rows (height).
- So, total squares = 5 × 4 =
20
✔ Area = 20 square cm
---
2)
Grid rectangle:
-
3 columns and
4 rows
- Total squares = 3 × 4 =
12
✔ Area = 12 square cm
---
3)
Grid rectangle:
-
6 columns and
3 rows
- Total squares = 6 × 3 =
18
✔ Area = 18 square cm
---
4)
Grid rectangle:
-
7 columns and
4 rows
- Total squares = 7 × 4 =
28
✔ Area = 28 square cm
---
5)
This is a rectangle with labeled sides:
- Length =
5 cm
- Width =
3 cm
- Area = 5 × 3 =
15
✔ Area = 15 square cm
---
6)
This is a square (a special type of rectangle):
- Side length =
4 cm
- Area = 4 × 4 =
16
✔ Area = 16 square cm
---
##
✔ Final Answers:
1)
20 square cm
2)
12 square cm
3)
18 square cm
4)
28 square cm
5)
15 square cm
6)
16 square cm
