Fill in the blanks :
The area of an irregular lamina is measured by using _________.

Answer 1

The area of lamina is equal to the sum of the areas of complete squares and that of squares half and more than half.

Let n be the total number of complete and more than half or half squares within the boundary of lamina.

Then, Area of lamina would be $=n\times 1c{m}^2$

[Since area of one big square is $1c{m}^2$]
