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

Complete the generic rectangle (PLEASE HELP)
navik [9.2K]

I believe the area of the blank rectangle, the biggest one, is 2800. The whole rectangle all together is 3225.

Explanation:

Since the length of one of the rectangles is 70, the rectangle with an area of 210 will have a side length of 3. This means the rectangle with an area of 15 has a side length of 5. <em>That</em> means the rectangle with an area of 200 has a side length of 40. Therefore, the blank rectangle has an area of 2800, as it's 2 side lengths are 70 and 40.
