Explanation:
Let’s go step by step for each shape. Remember, each little square = 1 cm².
a) Shape looks like a cat’s head.
- Count full squares inside the shape → about 28
- Now look at the partial squares (the ones cut by the line). If half or more is filled, count it as 1. If less than half, ignore.
→ You’ll find about 8 more partial squares that are mostly filled.
Total ≈ 28 + 8 = 36 cm²
b) Shape looks like a leaf or fish tail.
- Full squares: around 36
- Partial squares that are mostly filled: about 12
Total ≈ 36 + 12 = 48 cm²
c) Fish shape.
- Full squares: 24
- Partial squares (mostly filled): 6
Total ≈ 24 + 6 = 30 cm²
d) Big curved shape.
- Full squares: 34
- Partial squares (mostly filled): 8
Total ≈ 34 + 8 = 42 cm²
Tip: Don’t worry about being perfect — it’s called “estimating” for a reason! Just get close.
