We know Rhombus = all sides equal. So, equate the two sides, find x. Then, find value of one of the sides. Multiply by 4 for perimeter.

The perimter of a rhombus is 4 times the length of any one side.
& the sides of a rhombus are always congruent. 

5x+1=7x-11
-7x+5x=-11-1
-2x=-12
x=6

5(6)+1
31

The perimeter: 

4(31)=124
