Let’s solve each problem step by step.

Problems 1–6: Find the area by counting the squares.
Each small square = 1 unit of area.
Problem 1:
Blue rectangle — count the squares.
It has 4 columns and 3 rows → 4 × 3 =
12 squares
→ Area =
12
Problem 2:
Green rectangle — 2 columns, 3 rows → 2 × 3 =
6 squares
→ Area =
6
Problem 3:
Purple rectangle — 5 columns, 3 rows → 5 × 3 =
15 squares
→ Area =
15
Problem 4:
Pink shape — let’s count carefully:
Top row: 2 squares
Middle row: 2 squares
Bottom row: 4 squares
Total = 2 + 2 + 4 =
8 squares
→ Area =
8
Problem 5:
Blue shape — it looks like a “C” or frame.
Count each square:
Top row: 3 squares
Middle row: only rightmost square (1)
Bottom row: 3 squares
Total = 3 + 1 + 3 =
7 squares
→ Area =
7
Problem 6:
Yellow staircase shape — count row by row from top to bottom:
Row 1 (top): 2 squares
Row 2: 3 squares
Row 3: 4 squares
Row 4 (bottom): 5 squares
Total = 2 + 3 + 4 + 5 =
14 squares
→ Area =
14

Problems 7–9: Find the area by multiplying length × width.
Remember: Area = length × width
Units matter! The answer will be in square units (mm², cm², m²).
Problem 7:
Rectangle with sides 9 mm and 5 mm
Area = 9 × 5 =
45 mm²
Problem 8:
Rectangle with sides 8 cm and 2 cm
Area = 8 × 2 =
16 cm²
Problem 9:
Square with side 7 m (both length and width are 7 m)
Area = 7 × 7 =
49 m²
