Answer: 2 2/3 square feet is used for planting peas.
8 square feet is used for planting corn.
Explanation:
Isabella's mother has a garden with a total area of 10 2/3 square feet. Converting 10 2/3 square feet to improper fraction, it becomes 32/3 square feet.
If 1/4 of the garden will be used for planting peas, then the area of the garden that would be used for planting peas is
1/4 × 32/3 = 8/3 = 2 2/3 square feet.
If 3/4 of the garden will be used for planting corn, then the area of the garden that would be used for planting corn is
3/4 × 32/3 = 8 square feet
