Question 823231: If a side of a rhombus is 4n+7 and the perimeter of a rhombus is 20n +10 how do you find a side?

Perimeter = 4*(Side length)
P = 4*s
20n+10 = 4*(4n+7)
20n+10=16n+28
20n=16n+28-10
20n-16n=28-10
4n=28-10
4n=18
n=(18)/(4)
n=9/2
n = 4.5
-------------------------------------------------------
Side length
s = 4n + 7
s = 4*4.5 + 7
s = 25
So the side length is 25 units.
