Martha wants to build a rectangular wooden border around the perimeter of her children's playground. She can find the perimeter by using the formula 2w + 2l. The length, l, is 12 feet and the width, w, is 10 feet. What is the perimeter of Martha's wooden border?

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.
