First, you should know that one yard is 3 feet (1 yard = 3 ft).

Second, calculate the area of the Mcbeth's front yard in square feet. It is

A = (16*3)*(12*3) = 1728 .

Third, calculate how much of weed killer sells do you need to cover this area. To find this amount, use the proportion

= ,

where x is the unknown amount of weed killer sells in pounds.

It gives

= = pounds of weed killer sells.

The cost for this amount is $4.00 x 1.728 = $6.91.

It is the answer to your question.
