Question : What is the area of quadrilateral ABCD?

For area of the triangle we need to know the type of quadrilateral it is and also the dimensions of the sides

Statement 1: The given quadrilateral is a square

It gives us all properties but the length of any dimension (Side or Diagonal) is unknown hence

NOT SUFFICIENT

Statement 2: The given quadrilateral has a perimeter of 16.

This doesn't tell us any property of the quadrilateral which can make it a rectangle/parallelogram/square with same perimeter but rendering different results for area of the quadrilateral hence

NOT SUFFICIENT

Combining the Statement

We know it's Square with perimeter 16 i.e. side 4 therefore area of the quadrilateral = 4^2 = 16

SUFFICIENT

Answer: option C
