---- initial dimension
--- new width
--- new dimension
Required
The percentage increment
The length remains constant because only the width is extended.
The new area is:
Make L the subject
Substitute values for A and W
--- this is the length of the garden
Calculate the initial width:
Make W1 the subject
So, the initial area is:
The percentage change in area is:
Express as percentage
Question: 
There are two methods of doing this. One is via long division. It is long, and hard to type in a meaningful way, so I will not include that method. The other, which I often employ for dividing by small amounts such as 4, is to divide it in half 2 times. This is possible because 4 = 2 times 2. You now have the fractions
Therefore the solution is 90.
