Length of the sheep pen =60ft

150 ft of fencing bought

One side of rectangular sheep pen is covered with barn which is equaling the width

perimeter of rectangular sheep pen = 2(length +width)

length need to covered is 2 Length+ width

150 =2 length+width

150 = 2 x60 +width

150-120= width

30= width

Area of rectangle = 60 x 30

180 ft2
