The correct answer is [A]

Rectangle has 2 pairs of equal sides which are opposite to each other.
i.e (x + 7 ) = ( 3x -11) = Length
x + 7 = 3x -11
Collect like terms together
X + 7 = 3x -11
X -3x = -11-7

- Length = x + 7 = 9 + 7 = 16 cm
- Width = x + 1 = 9+1 = 10 cm
- Perimeter = 2 ( l +w)
= 2( 16 +10)
=2(26)
= 52 cm
