the perimeter of the flower garden is 30 feet. If the width of the flower garden is 3 feet, what is the length?

nadezda [96]

Answer:

12 feet

Step-by-step explanation:

First, you should know that perimeter is equal to the sum of all the sides. If the flower garden is a rectangle, the width on the other side is also 3. 3+3 equals 6. Next, subtract 6 from 30 to get 24. Now, divide 24 by 2 to get the length of 1 side. 24/2 equals 12. So the length is 12 feet

Does dose anyone know how to solve this?

solniwko [45]

Answer:

Width of rectangle = 6 m

Length of rectangle = 11 m

Step-by-step explanation:

Let width of rectangle = w

Length of rectangle = 3w-7

Area of rectangle = 66 m²

We need to find length and width of rectangle

The formula used is: $Area=Length \times Width$

Putting values and finding w

$Area=Length \times Width\\66=(3w-7)(w)\\66=3w^2-7w\\3w^2-7w-66=0\\$

Solve using quadratic formula: $w=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

We have a=3, b=-7, c=-66

Putting values and finding w

$w=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\w=\frac{-(-7)\pm\sqrt{(7)^2-4(3)(-66)}}{2(3)}\\w=\frac{7\pm\sqrt{49+792}}{6}\\w=\frac{7\pm\sqrt{841}}{6}\\w=\frac{7\pm29}{6}\\w=\frac{7+29}{6}\:,\:w=\frac{7-29}{6}\\w=6, w=-3.6$

We get values of w as w=6 and w=-3.6

As we know width cannot be negative, so considering w = 6

So, Width = 6

Length = 3w-7 = 3(6)-7 = 18-7 = 11

So, Width of rectangle = 6 m

Length of rectangle = 11 m

The population density is approximately 4 people per square mile

<h3>Calculating Population Density </h3>

From the question, we are to determine the population density

Population density is given by the formula,

$Population\ density = \frac{Number\ of\ people}{Land\ area}$

Number of people in the town = 12620 people

Now, we will determine the land area of the town

From the given shape,

Land area of the town = (60 × 65) - (25 ×40)

Land area of the town = 3900 - 1000

Land area of the town = 2900 square mile

∴ Population density = $\frac{12620}{2900}$

Population density = 4.3517

Population density ≅ 4 people per square mile

Hence, the population density is approximately 4 people per square mile
