You copy a 10 cm x 10 cm picture onto a 4 m x 4 m wall, and divide both images into grids. If each box in the picture is 1 cm x 1 cm, how big is each box on the wall? *

4 cm
40 cm
400 cm
1 meter

What do you mean by this?

Iwould go with write exactly two extra paragraphs to point out additional information. but the keyword "exactly" throws me off. leads me to believe it's d. go with your gut feeling. either "write exactly two extra paragraphs" or "none of these".
