<span>It was given that the garage is in the shape of a square, which means that all the sides are equal. It was also given that one of the sides of the garage is equal to the length of her rabbit pen. The length of a rectangular shape is the longer side of the rectangle. Hence from the given dimension of the rectangular pen of 16 by 10, the length is 16 and hence the measure of one side of the garage. The area of a square is given by s^2, where s is the measure of one of the sides. Therefore, the area of the garage = 16^2 = 256 square units.</span>
