Ronald is changing the shape of his backyard from 100 feet long by 22 feet wide to a square that has the same area. What is the perimeter of the square backyard, rounded to the nearest whole number?
The perimeter is 550 feet all around. when you multiply 100 and 22 to find the area you get 2,200. Divide that by 4 because for a square to be a square all for sides must be equal. So your answer would be 550 ft.
