The length of side walk is 500 feet
<em><u>Solution:</u></em>
Given that, A rectangle park measures 300 ft by 400 ft
Length = 300 feet
Width = 400 feet
A sidewalk runs diagonally from one comer to the opposite corner
We have to find the length of side walk
Which means, we have to find the length of diagonal of rectangle
<em><u>The diagonal of rectangle is given by formula:</u></em>

Where,
d is the length of diagonal
w is the width and l is the length of rectangle
<em><u>Substituting the values in formula, we get</u></em>

Thus length of side walk is 500 feet

Answer:
Step-by-step explanation:
Given that Amir is sorting his stamp collection. He has made a chart of what countries the stamps are from 
He got results as
France 1/3  
Morocco 5/12  
Spain 1/6 
To find out what fraction of Amir's stamps are from France, Morocco, or Spain, we have to simply add the three as there is common element between any two pairs
Hence answer is

 
        
                    
             
        
        
        
quotient is 98 1/2   
 
 
           <u> 0098 </u> 14/28
     28 | 2758
          <u>  252  </u>    * 9 x 28 
              238 
           <u>   224 </u>   * 8 x 28
                14
2758 ÷ 28 = 98 14/28  simplified to 98 1/2
