Camila wanted to create a second garden to grow even more vegetables. To determine the dimensions of her second garden, she used
OlgaM077 [116]

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:

h = 0.75(10) = 7.5

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

h = 1.5(10) = 15
