Question
A running track of 440 ft. is to be laid out enclosing a foot ball field, the shape of which is a rectangle with a semi – circle at each end. If the area of the rectangular portion is maximum, the lengths of the sides are
- 100 ft., 60 ft.
- 70 ft, 50 ft.
- 90 ft, 70ft.
- 110 ft, 70ft
The correct answer is: 110 ft, 70ft
