Question

5. Find the approximate area of an irregular lamina
of which boundary line is drawn on the graph
paper shown in Fig. 1.16. below​

Answer 1

In the figure,

we can see that there are 11 full squares.

we can also see that there are 9 squares which are more than a half.

total number of squares $\large\rm { = 9+11}$

$\large\rm { = 20}$

area of 1 square = $\large\rm { 1 \times 1}$

$\large\rm { = 1 \ cm^{2}}$

area of 20 squares = $\large\rm { 20 \times 1}$

$\large\tt{\boxed{\fcolorbox{lime}{orange}{ 20 cm²}}}$ is your answer.

Answer 2

Answer:

hii friend ,

area of square:- s×s

= 1×1

=1cm

here they asked 20 sq

so 20×1

=20cm

i hope it helps you.
