A square flower garden has a perimeter of 10 feet. Duncan uses stones to edge the garden. Each stone is 𝟣𝟤one-half-foot long. How many stones will Duncan need to edge the garden?

Answer 1

He will need 20 stones.

If each stone is 1/2 foot long and the perimeter of the garden is 10 feet, you would need to multiply 10 by 1/2 or 0.5 to get to 20. To check your work, draw a rectangle that is 10 inches in perimeter, then measure each stone as 0.5 or 1/2 inch.

Answer 2

10 feet * 1 stone = 20 stones

----------

0.5 feet
