Let’s solve each rectangle one by one.
We are told: To find the area of a rectangle, count the number of squares inside it.
Each square is 1 cm × 1 cm, so each square = 1 square cm.
So we just multiply the number of rows by the number of columns (or count all the little squares).

Problem 1)
Rectangle has 2 rows and 6 columns.
Number of squares = 2 × 6 =
12
Area =
12 square cm
---
Problem 2)
Rectangle has 3 rows and 3 columns.
Number of squares = 3 × 3 =
9
Area =
9 square cm
---
Problem 3)
Rectangle has 5 rows and 4 columns.
Number of squares = 5 × 4 =
20
Area =
20 square cm
---
Problem 4)
Rectangle has 4 rows and 6 columns.
Number of squares = 4 × 6 =
24
Area =
24 square cm
---
Final Answer:
1) Area = 12 square cm
2) Area = 9 square cm
3) Area = 20 square cm
4) Area = 24 square cm
