The lengths of the sides of a quadrilateral are consecutive even integers. twice the length of the shortest side plus the length
spayn [35]
To solve this problem you must apply the proccedure shown below:

 1. You have the following information given in the problem above: <span>twice the length of the shortest side plus the length of the longest side is 248 inches.

 2. Therefore, keeping on mind the information above, you have:

 x: the shortest side
 x+6: the longest side

 2x+(x+6)=248
 3x+6=248
 3x=242
 x=242/3
 x=80.66 (The shortest side)

 x+6=80.66+6=86.66 (The longest side)

 The answer is: 86.66
