Answer:
38m
Step-by-step explanation:
Area of rectangle = length x breadth
perimeter of a rectangle = 2 x( length + breadth)
The factors of 18 are 1,2, 3,6,9,18
The possible areas and perimeters of the flowerbed based on the factors are
1 x 18 = 18cm^2 Perimeter = 2(1+18) = 38
2 x 9 = 18cm^2 perimeter = 2 (2+9) = 22
3 x 6 = 18cm^2 perimeter = 2 (6 +3) = 18
the greatest is 38m
