A rectangular garden is 6 feet long and 4 feet wide. A second rectangular garden has dimensions that are double the dimensions o
Talja [164]

Percent change is 100%

Step-by-step explanation:

  • Step 1: Find the perimeter of the first garden when length = 6 ft and width = 4 ft

Perimeter = 2 (length + width)

                = 2 (6 + 4) = 2 × 10 = 20 ft

  • Step 2: Find the perimeter of the second garden when length = 12 ft and width = 8 ft (∵ dimensions are doubled)

Perimeter = 2 (12 + 8) = 2 × 20 = 40 ft

  • Step 3: Find the percent change in perimeter

Percent Change = Final value - initial value/Initial Value × 100

                            = (40 - 20/20) × 100

                            = 1 × 100 = 100%
