Find the area of a sweet shop if it occupies 2.5% of the area of the zoo, the area of the zoo is 400 m2.

1. To solve the problem, you need to find 2.5% of the area of the zoo. Then let us first find out what 1% of the area of the zoo is equal to, dividing its area by 100%, we get:
400 m2 / 100 = 4 m2.
2. Now we can calculate the area of a candy store by multiplying the area of 1% of the zoo by 2.5, we get:
2.5 * 4 m2 = 10 m2.
Answer: The sweet shop has an area of only 10 m2.
