Using proportions, considering original measures of 10 feet, we have that:
- The horizontal measurement of the second garden is of 7.5 feet.
- The vertical measurement of the second garden is of 15 feet.
<h3>What is a proportion?</h3>
A proportion is a fraction of total amount.
In this problem, the total amount is the original measures of 10 feet.
The horizontal measurement has a scale factor of 75%, hence:

The vertical measurement has a scale factor of 150%, hence:

Hope I wrote this clearly
2x + 2(5+x)=10
2x+10+2x=10
4x+10=10
4x=0
X=0
