ok ... in this situation... we need to find the area of the rectangle first as it is equal to the area of square . 
so .... area of rectangle = l×b= 16×4
= 64 ∴area of square = 64 
area of square = s×s
∴to find one side of the square ... we need to find the root of 64 = 8 
∴one side = 8 
now : perimeter of square : 4 × sides = 4 × 8 = 32 ║
