Was there a typo in the possible answers by any chance? B is closest to the possible answer, but only if the division sign was a multiplication sign.

Lorena is designing a rectangular patio in her garden. She has enough tiles to cover 324 square feet. She wants the length of th
IceJOKER [234]

Using the area of a rectangle, it is found that her patio should have a width of 12 feet and a length of 27 feet.

<h3>What is the area of a rectangle?</h3>

The area of a rectangle of length l and width w is given by:

A = lw.

In this problem:

  • She has enough tiles to cover 324 square feet, hence A = 324.
  • She wants the length of the patio to be 15 feet longer than the width, hence l = 15 + w.

Thus:

324 = w(15 + w)

w^2 + 15w - 324 = 0

w = -27 or w = 12.

We take the positive value, hence l = 15 + w = 15 + 12 = 27 feet.

The dimensions should be a width of 12 feet and a length of 27 feet.

What is the answer to this somebody!!!
Fed [463]

Use the geometric mean for right triangles as the sides are related to the hypotenuse. 30 - 6 = 24. We need that for our proportion. \frac{24}{x}=\frac{x}{30}. We cross-multiply to get x^2=720. Taking the square root of both sides gives us that x=12\sqrt{5}, the second choice above.
