Given the garden plot is rectangular in shape.
the area of rectangle is given by calculating the product of its length and its width.
Given the dimensions of rectangle are:-
Length (l) = 3 yd
Width (w) = 2 ft = 2/3 yd
[tex]area = l \times w = 3 \times \frac{2}{3} = 2 \: {yd}^{2} [/tex]
Hence, option B i.e. 2 sq yd is the final answer.
