The perimeter, P, of a rectangle with length l and width w is given by the formula P = 2l + 2w. The area, A, is given by the formula A = lw. In Exercise, use these formulas to find the perimeter and area of each rectangle. Express answers in simplified radical form. Remember that perimeter is measured in linear units, such as feet or meters, and area is measured in square units, such as square feet, ft2, or square meters, m2.
