Maggie has a square piece of origami paper that has an area close to 200 cm2. What is a good approximation for the length of one side of her paper?
A.
50 cm
B.
8 cm
C.
14 cm
D.
20 cm
D. 20 cm
To find the approximate length of one side of the square paper, we can take the square root of the area. The square root of 200 cm² is approximately 14.14 cm. Rounding to the nearest whole number, we get 14 cm. Choice D, 20 cm, is the closest approximation.
