Answer:
They can plant 12 pumpkins.
Explanation:
First we calculate the area of the rectangle for pumpkins:
Area = side * side
Area = 30 cm * 10 cm
Area = 300 cm²
Then we divide that area by the space required by one pumpkin, to calculate how many pumpkins they can plant:
300 cm² / 25 cm² = 12
So the Ladybugs can plant 12 pumpkins.
