<em>The length of the square that has the same perimeter as the rectangle is of length 6cm and area of 48cm² is 7cm</em>
<h2>
Explanation:</h2>
Let's call:

From the question, we know that:
- <em>A rectangle and a square have the same perimeter.</em>
So:

Moreover:
- <em>The rectangle is of length 6cm and has an area of 48cm²</em>
Accordingly:

Also:

From the statement of perimeters:

Finally, <em>the length of the square that has the same perimeter as the rectangle is of length 6cm and area of 48cm² is 7cm</em>

Solving (a): The coordinates of K
The parallelogram has the following diagonals: IJ and HK
Diagonals bisect one another. So:
Midpoint of IJ = Midpoint of HK
This gives:




Multiply through by 2

By comparison:


Solve for x and y


So, the coordinates of k is:

The length of JK is calculated using distance (d) formula

---- 
So:





Hence:

Answer:
The rate of change is -5
The initial value is 25
Step-by-step explanation:
Since, this is a linear relation
so, we can select any two points and find equation of line
points are (1,20) and (3,10)
so,


now, we can find slope

now, we can plug values


now, we can use point slope form of line

now, we can plug values

now, we can solve for y

we know that
slope is the rate of change
So, the rate of change is -5
For finding initial value , we can plug x=0 and find y


So, initial value is 25
68(2)
68 x 2 =
136
Your answer is 136
