Question

Calculate the approximate area of the banana leaf, if each square is of the area $1{\text{cm}}^2$.

• A. 17

Answer 1

The correct option is A 17
Given:
No. of complete squares on the banana leaf : $n_1=11$
No. of squares which are more than half covered : $n_2=6$
No. of squares which are half covered : $n_3=0$
Total no. of squares covered:
$n=n_1+n_2+n_3\times \frac{1}{2}=11+6+0=17$

Since 1 square in the grid has an area $1{\text{cm}}^2$, the approximate area covered by the leaf is:
$17\times 1=17{\text{cm}}^2$
