The boundary line of an irregular lamina...

The boundary line of an irregular lamina, on a graph paper is shown in Fig. Find the approximate area of the lamina. In Fig. , the number of complete squares = 14
The number of squares more than half = 11

Text Solution

Verified by Experts

Total number of squares n = 14 + 11 = 25
Area of the square = 1 cm x 1 cm = `1 cm^2`
Area of lamina = `25 xx 1 cm^2 = 25 cm^2`
