Final answer:
To find out how many feet of flowers Amanda will have around her garden, calculate the perimeter by doubling the sum of the length and width. Amanda's rectangular garden measures 3 feet by 5 feet, so the total length of flowers around it will be 16 feet.
Step-by-step explanation:
The subject of this question is Mathematics, and it involves calculating the perimeter of a rectangular garden to determine the total length of flowers Amanda will have around her garden. Assuming Amanda wants to plant flowers along the entire perimeter of the garden, we need to add the lengths of all four sides to get the total feet of flowers.
To calculate the perimeter of a rectangular area, we use the formula:
Perimeter = 2 × (Length + Width)
For Amanda's garden, which has a length of 3 feet and a width of 5 feet:
Perimeter = 2 × (3 feet + 5 feet) = 2 × 8 feet = 16 feet
So, Amanda will have 16 feet of flowers around her garden.
