A rectangular plot of land measures 24 feet by 18 feet. What is its area in square yards? (1 yard = 3 feet)

First find the area in square feet: $24\cdot18=432$. One yard is $3$ feet, so one square yard is $3\cdot3=9$ square feet. Divide: $\frac{432}{9}=48$ square yards, choice H. You can also convert each side first: $8$ yards by $6$ yards is $48$. Choice J ($432$) leaves the answer in square feet. Choice G ($36$) divides by $12$, as if converting feet to inches. Choice F ($16$) divides by $27$, the number of cubic feet in a cubic yard, which applies to volume and not to area. Area conversions use the square of the length conversion factor.
