From figure, the number of complete squares = 11
The number of squares more than half = 9
∴ Total number of squares = 11 + 9 = 20
∴ Area of the 1 square = 1 cm × 1cm = 1 cm2
∴ Area of 20 squares = 20 × 1 cm2 = 20 cm2
∴ Approximate area of irregular lamina = 20 cm2

Answer:
20 cm²
Explanation:
No. of complete squares = 11
No. of half or more-than half squares = 9
Total no. of squares = 20
Area of 1cm = (1 × 1) cm²
= 1 cm²
∴ Area of 20 squares = (20 × 1 cm²)
∴ 20 cm² (Answer)
