sarah is making a square shaped sandbox for her little brother. If the base of the sandbox has an area of 17 square feet, approximately how long is each side of the sandbox

about 4.25

you get this answer from dividing the 17 into four sides because it has four sides and if each side is equal then you divide 17 divide by 4 which you get 4.25. if you need to check your work then just do 4.25 x 4 and if you get the answer you started with then your answer is right. you can also do 17 divide 4.25 to check your work.
