a rectangular garden is fenced on alls ides with 256 feet fencing. the garden is 8 feet longer than it is wide
pickupchik [31]

The length and width of the rectangular garden is estimated as-

  • Length = 68 ft
  • width= 60 ft
<h3>How to calculate perimeter of the rectangle?</h3>

A rectangle's perimeter is the total length and distance of its border across all sides. The perimeter of a rectangular box is a linear measurement that is expressed in meters, feet, cm, or yards. Let us first examine the two primary characteristics of a rectangle.

  • A rectangle's four angles are all 90°.
  • A rectangle's opposite sides are of equal length.

The perimeter of the rectangle is given as-

Perimeter = 2(length + width)

perimeter= 256

Let the width of the rectangle be x.

Length is 8 feet longer than width, Thus,

length = x+8

Substitute the values in the formula of perimeter;

256 = 2( x+ 8+ x)

256 = 2( 2x + 8)

128= 2x + 8

120= 2x

x=60

Thus, width = 60 ft.

Length = 60 + 8 = 68 ft.

Therefore, the length and width of the rectangular garden is estimated.

The equation Y equals 4/10 X describes the number of kilometers y that a van travels in x minutes. What is the constant speed of
Mekhanik [1.2K]

Answer:

\frac{4}{10}=0.4 kilometers per hour.

Step-by-step explanation:

We have been given an y=\frac{4}{10}x, which describes the number of kilometers y that a van travels in x minutes. We are asked to to find the constant speed of the van in terms of hours.

We can see that van travel \frac{4}{10}x kilometers in x hours. To find the constant speed of van, we will substitute x=1 in our given equation as:

y=\frac{4}{10}(1)

y=\frac{4}{10}

Since van travels \frac{4}{10} kilometers in one hour, therefore, constant speed of van is \frac{4}{10} kilometer per hour or 0.4 kilometers per hour.
