We can find the area of any parallelogram (including rectangles) by doing the base times the height, as long as the base and height are perpendicular. That is true in these cases as well, even when the side lengths are square roots. We can find the perimeter by adding up the sides. An exact answer leaves the perimeter with square roots in the answer (like combining like terms with similar roots), or we can use our calculators to find decimal approximations.
