The width of rectangle = 15 feet .

Step-by-step explanation:

<h2>Given = </h2>
  • Perimeter of rectangle = 80
  • Length of rectangle = 25 feet
<h2>To Find = </h2>
  • width or Breadth of rectangle.

As we know ,

Perimeter of rectangle = 2× (L + B )

  • where L is Length and B is width or Breadth.

Filling values in the formula :-

=> 80 = 2 ( 25 + B )

  • we don't know the value of ' B' so we put ' B' as it is .

=> 80/2 = 25 + B

=> 40 = 25 + B

  • when we combine like terms one side signs will be changed from + to - .

=> B = 40 - 25

=> B = 15 feet .

<h2>________________</h2>

Properties of rectangle :

  1. It is a quadrilateral
  2. each angle is 90° .
  3. sum of angles is 360°
  4. Opposite sides are equal.
  5. Diagonals bisect each other.

Perimeter of rectangle = 2× L+B

Area = L×B .

  • Given - <u>a </u><u>rectangle </u><u>with </u><u>length</u><u> </u><u>2</u><u>5</u><u> </u><u>feet </u><u>and </u><u>perimeter </u><u>8</u><u>0</u><u> </u><u>feet</u>

  • To calculate - <u>width </u><u>of </u><u>the </u><u>rectangle</u>

We know that ,

\bold{Perimeter \: of \: rectangle = 2(l + b)} \\

where <u>b </u><u>=</u><u> </u><u>width </u><u>/</u><u> </u><u>breadth</u> of rectangle

‎ ‎ ‎

<u>substituting</u><u> </u><u>the </u><u>values </u><u>in </u><u>the </u><u>formula </u><u>stated </u><u>above </u><u>,</u>

\bold{80  = 2(25 + b)} \\  \\\bold{ \implies \: 25 + b = \cancel \frac{80}{2} } \\  \\ \bold{\implies \: 25 + b = 40 }\\  \\ \bold{\implies \: b = 40 - 25 }\\  \\\bold{ \implies \: b = 15 \: feet}

It's a bit of a bummer to have to work through all of these to find the answer. That a lot of slope calculations (or graphing, or whatever). When there are this many, a spreadsheet or other machine help can make it easier.

The correct choice is the last one, XYZ, with vertex X being where the right angle is located.

_____
Slope of XY is 4/7; slope of XZ is -7/4. The product of these is -1, so those segments are at right angles.

What is the estimated margin of error, using standard deviation?
OLEGan [10]
Find the mean ( average):
105 + 104 + 110 + 112 + 114 + 106 + 108 +109 = 868
Mean = 868 / 8 = 108.5

Standard deviation:
108.5 - 105 = 3.5, 3.5^2 = 12.25
108.5 - 104 = 4, 4^2 = 16
110 - 108.5 = 1.5, 1.5^2 = 2.25
112 - 108.5 = 3.5, 3.5^2 = 12.25
114 - 108.5 = 5.5, 5.5^2 = 30.25
108.5 - 106 = 2.5, 2.5^2 = 6.25
108.5 - 108 = 0.5, 0.5^2 = 0.25
109 - 108.5 = 0.5, 0.5^2 = 0.25

12.25 + 16 +2.25 + 12.25 + 30.25 +6.25+0.25+0.25 = 79.75
79.75/8 = 9.96875, SQRT(9.96875) = 3.1573

Standard Deviation = 3.1573

108.8 +/- 1.96 *(3.1573/sqrt(8) = 110.687 and 106.312

110.687 - 108.5 = 2.19
108.5 - 106.312 = 2.19
 

Margin of error = +/- 2.19
