Open in App
Solution

The correct option is A 17
Given:
No. of complete squares on the banana leaf : n1=11
No. of squares which are more than half covered : n2=6
No. of squares which are half covered : n3=0
Total no. of squares covered:
n=n1+n2+n3×12 =11+6+0 =17

Since 1 square in the grid has an area 1 cm2, the approximate area covered by the leaf is:
17×1=17 cm2
