Answer: 5980 square feet
Step-by-step explanation: We know that Richard can apply fertilizer to 4485 square feet = 3/4 hour. To solve this problem, one approach is to find 1/4 then multiply by 4 to get the whole 4/4 or 1 hour. So the solution would be: 4485/3=1495 Then multiply this by 4. 1495 multiplied by 4 is equal to 5980 square feet. So Richard can apply fertilizer to 5980 square feet in 1 hour. This is solved by an anonymous 10-year-old girl.
