A rectangular lot is 60 yards wide and 100 yards long. Give the length and width of another rectangular lot that has the same perimeter but a larger area.

Question

How do you solve this question?

Answer 1

The closer to being square the rectangle is, the more efficient use of the fixed perimeter.  So 80 yds by 80 ft yds still has the same perimeter (320 yds) but 6400 sq yd area, as opposed to 6000 sq yds.
