Answer:

11.33 * 16.33 meters to the nearest hundredth.

Step-by-step explanation:

Let the width of the pool be x meters, then the length is x+5 meters.

The length of whole area = x + 5 + 2(3)  = x + 11 meters and the width is

x + 2(3) = x + 6 meters.

So we have the equation (x + 6)(x + 11) = 387.

x^2 + 17x + 66 = 387

x^2 + 17x - 321 = 0

x =  [-17 +/- sqrt (17^2 - 4*1*-321)] / 2

x = 11.33 meters

So the width is 11.3 m and the length is 16.33 meters.

Which of the following(s) is true of a rectangle?
arsen [322]
<h2>Explanation:</h2>

Let's take a look at all of our options.

A. it is also a square

  • A rectangle is NOT <em>always </em>a square because a square has congruent sides, so that means all four of its sides are <em>always </em>equal.
  • A rectangle <em>can </em>be a square but it can also not be a square, so therefore A cannot be an option because it is not always true about a rectangle.

B. the sum of its angle measures is 360

  • This is true because every quadrilateral's angle measures will add up to 360 degrees, no matter what. This is like how a triangle's angle measures always add up to 180 degrees.
  • B is an option because it is an ALWAYS true statement.

C. it has four congruent angles

  • A rectangle always has 90 degree angles, giving it its shape.
  • Since a rectangle always has the same-degree angles, that means that it DOES have four congruent angles.
  • C is also an option because it is always true.

D. it has four congruent sides

  • A rectangle does not ALWAYS have four congruent sides. Say for example a rectangle has a longer length than its width.
  • A square has four congruent sides, but a rectangle is not always a square, therefore this option is not applicable for a rectangle since it is not always true.
<h2>Answers:</h2>

B and C are always true of a rectangle.
