Answer:
the answer is c
Step-by-step explanation:
The perimeter of rectangle is 2(x+y).
if we subtract 5 from length and breadth then the equation will be 2(x-5+y-5).
The perimeter after subtracting 5 is 26 then,
2(x-5+y-5)=26
2(x+y-10) =26
2x+2y-20 =26
2x+2y=26+20
2(x+y)=46
x+y=46/2
x+y=23
Hence,answer is Option C
