16 x 0.42 = 6.72
What is the greatest perimeter of a rectangle with an area of 39 sq. ft.?
Answers
To find the answer you do 39×4. You multiply by 4 because there are 4 sides.
This will be the biggest number.
Rectangle A: -- Length = 20-ft, Width = 10-ft. -- Area = 200 square ft -- Perimeter = 60-ft
Rectangle B: -- Length = 16-ft, Width = 12.5-ft -- Area = 200 square ft -- Perimeter = 57-ft
Rectangle C: -- Length = 40-ft, Width = 5-ft -- Area = 200 square ft -- Perimeter = 90-ft
Rectangle D: -- Length = 50-ft, Width = 4-ft -- Area = 200 square ft -- Perimeter = 108-ft
Rectangle E: -- Length = 100-ft, Width = 2-ft -- Area = 200 square ft -- Perimeter = 204-ft
