Answer 1

It must be a square, find the sides, then the area

Answer 2

is myy procedure correct
first i made a square 52/4=13
than i try changing the square to a rectangle by multiplying 16x13 but the answer was 208
than i did 14x12 which is 168 and that was one of the choices

Answer 3

A square of sides 13 has a perimeter of 52 and its area will be 13 x 13 or 169, which is larger than 168.

I sure hope 169 is one of your choices or else they are wrong.

BTW a square is a rectangle.
