Find the area of a square with apothem 9 in. round to the nearest whole number.
281 in2
305 in2
458 in2
324 in2

The apothem is the line from the center of the polygon (square) to the midpoint of a side.

So, if the apothem is 9in, the length of the side is 2 * 9in = 18 in.

And, the area of the square is (length of the side)^2 = (18 in)^2 = 324 in^2
