Answer:  
=====================================================
Reason:
Plot the points (0,0) and (r,s). You can place (r,s) anywhere you want. 
Connect the two points mentioned and form a right triangle such that the segment from (0,0) to (r,s) is the hypotenuse of said right triangle. 
The horizontal leg has a length of r-0 = r units, while the vertical leg will be 's' units. 
Check out the diagram below.
We then apply the pythagorean theorem to say  where h is the hypotenuse. Solving for h gets us
 where h is the hypotenuse. Solving for h gets us  . We only focus on the positive square root since a negative hypotenuse makes no sense.
. We only focus on the positive square root since a negative hypotenuse makes no sense.
Since we made the hypotenuse the segment with endpoints (r,s) and (0,0), this means the hypotenuse length and the distance are the same thing. 
Therefore, the distance from (r,s) to (0,0) is 
As an alternative, you can use the distance formula to get the same answer. The distance formula is effectively the pythagorean theorem phrased a different way.
 
        
             
        
        
        
Answer:
The length of the rectangle is 9 cm
Step-by-step explanation:
Given: The length of rectangle(l) = (x+3) cm and a width of rectangle (w) =  cm a
 cm a
Also, perimeter of rectangle is 24 cm.
Perimeter of rectangle is to add the lengths of all the four sides. 
Perimeter of rectangle (P) is given by;
P=2(l+w) 
Substituting the value of P = 24 cm , l = (x+3) cm and w =
then,  

Divide by 2 both sides of an equation;

Combine like terms;

Subtract 3 from both the sides we get;

Simplify:

Multiply both sides by  we get
 we get

Therefore, length of rectangle(l) = (x+3) = 6+3 = 9 cm
