Answer:
2 2/3 ft^2
Step-by-step explanation:
The area of the garden is 10 2/3 ft^2. She used 1/4 of it for the peas.
Multiply 1/4 times the total area to find the amount used for peas.
10 2/3 * 1/4
Change the mixed number to an improper fraction.
(3*10+2)/3 * 1/4
32/3 * 1/4
8/3
Change this back to a mixed number. 3 goes into 8 2 times with 2 left over.
2 2/3 ft^2
This is how much is used for the peas.
