One container of fertilizer covers 900 square feet. A property has a rectangular backyard that is 30 feet long and 20 feet wide. The front yard is triangular with a base of 24 feet and a height of 12 feet. What percentage of the container will be used on the property? Round to the nearest percentage.

The backyard area is 30 × 20 = 600 square feet, and the triangular front yard is (24 × 12) ÷ 2 = 144 square feet. Together, they cover 744 square feet, so the fraction of the container used is 744 ÷ 900 ≈ 0.827, or about 83%. The correct choice is 83%.
