What is the largest possible perimiter of a rectangle with an area of 25ft2?

Answer 1

The smallest possible perimeter is 20-ft, but there is no largest possible perimeter.

You can make it as large as you want, with no limit.

Examples:

5-ft x 5-ft . . . . area = 25 ft2 . . . perimeter = 20 ft

2.5-ft x 10-ft . . area = 25 ft2 . . . perimeter = 25 ft

1-ft x 25-ft . . . area = 25 ft2 . . . Perimeter = 52 ft

6-in x 50-ft . . . area = 25 ft2 . . . Perimeter = 101 ft

3-in x 100-ft . . area = 25 ft2 . . . perimeter = 2001/2 ft

1-in x 300-ft . . area = 25 ft2 . . . perimeter = 6001/6 ft

0.1-in x 3,000-ft . . area = 25 ft2 . . . perimeter = 6,0001/60 ft
