Perimeter = yd Area = yd$^{2}$
To determine the are of a figure you simply add the lengths of the sides together. Since there is no multiplication involved, the unit will never change. Therefore the unit for perimeter is "yd". To determine the area you multiply the length times the width of the object. Since you would be multiplying the same unit of measure together the unit for area is yd$^{2}$.
