We know that 98mm is the 100% of the diameter of the plant before James watered with the magical solution; after he watered, the diameter of the plant grew to 188.869mm. Let 
be the grew in the percentage of the diameter.
Now we can establish a ratio and solve for:
%
Now that we know the diameter of the plant grew 192.7%, we just need to divide that quantity by 100% to find how many times the diameter grew:
We can conclude that the diameter of the peach <span>become approximately 1.9 times larger after James watered it.</span>
Now we can establish a ratio and solve for

The area of a rectangle is given by the multiplication of its dimensions:
In this case, we have an exact value for the area, and two variable expressions for width and length. Let's replace the formula above with what we're given:
If you expand the right hand side, you have
And if you move all terms to the right hand side, this becomes
This is a quadratic equation, since it is in the form , where
If you plug these values in the generic formula
you get
Let's see which dimensions they yield:
But the dimensions of a rectangle can't be negative, so we can't accept this answer.
The other solution yields
So these are the dimensions of the rectangle
