2. The area of a square is
324 sq. meters. What is the
perimeter?

72 meters

Step-by-step explanation:

The area of the square we are told is 324. With this, we know the area of a square is found by squaring base times height. In order to find the length of one side, find the square root of 324, which is 18. Because it is a square we know all sides are equal, so we can find the perimeter by multiplying 18 by 4, or adding all sides.
