Answer: The perimeter of Martha's wooden border = 44 feet.
Step-by-step explanation:
Given: The formula to find the perimeter = 2w + 2l. , where w = width and l = length
If l= 12 feet and w = 10 feet
Then, the perimeter of Martha's wooden border = 2(10)+2 (12) feet
The perimeter of Martha's wooden border = 20+24 feet
The perimeter of Martha's wooden border = 44 feet
Therefore, the perimeter of Martha's wooden border = 44 feet.
