Question

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?

Answer 1

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.
