$6000 ft^2$
To compute the area, you must first convert the measurements to the same unit of measure. Since the answer is in square feet, convert to feet. $100\ yd=100\ yd\times\frac{3\ ft}{1\ yd}=300\ ft$ Use the formula for the area of a rectangle, and substitute the given values. $A=bh=(20\ ft)(300\ ft)=6000\ ft^2$
