Answer:

Width=13 Length=25

Step-by-step explanation:

The total perimeter of the field is 76 feet.

Lets say that is length is X and the width is Y.

The equation would be:

2Y+2(12+Y)=76

First solve for the parenthesis.

2Y+24+2Y=76

76-24=52

52=4y

y=13

To check your answer, 13 times 2 (26) plus 25 times 2 (50)= 76 so we know this is correct.

B. 2

Step-by-step explanation:

For x = 2, w(x) = 3, t(x) = - 1

w(x) + t(x) = 3 + (-1) = 3 - 1 = 2

The park shown is in the shape of a square. Is the perimeter rational or irrational? Area = 24,200 yd 2

romanna [79]

Answer:

Perimeter is irrational

Step-by-step explanation:

The attachment is missing but the question is still answerable

Given

$Area = 24200 yd^2$

Required

Determine if the Perimeter is rational or not

First, we need to determine the sides of the square;

$Area = Length * Length$

Substitute $Area = 24200 yd^2$

$24200 = Length * Length$

$24200 = Length^2$

Take Square root of both sides

$\sqrt{24200} = Length$

$Length = 155.563492$

The perimeter of a square is calculated as:

$Perimeter = 4 * Length$

$Perimeter = 4 * 155.563492$

$Perimeter = 622.253968$

Because the value of perimeter can't be gotten by dividing two integers, then perimeter is irrational
