We can use 4 yards as the unit for the dimensions. And let the dimensions be a * b, then we have one side will have a+1 posts (including corners) and the other b+1 (see example diagram below with a=4 and b=3). The total number of posts is 2 (a+b)=20. Solve the system b+1=2 (a+1) and 2 (a+b)=20, We get: a=3 and b=7. AMC 10 Problems and Solutions. AMC 10 problems and solutions. Year. Test A. Test B. 2022. AMC 10A.
