Requires
Determine the number of bags to cover the whole garden
This is calculated as thus;

Expand the numerator



Express 81 as 9²

Evaluate as difference of two squares


Hence, the number of bags is 
We can write a proportion to resemble the problem;
AE/ED = AB/BC
AE = 9
ED = 6
AB = x
BC = 10
Substitute with the given values.
9/6 = x/10
9/6 * 10 = x/10 * 10
90/6 = x
15 = x
Therefore, the answer is 15.
Best of Luck!
