Answer: 60 feet
Step-by-step explanation:
To find the least amount of fencing needed to enclose a garden that is 20 feet by 10 feet, you can follow these steps: 1. Calculate the perimeter of the garden: Perimeter = 2(length) + 2(width) 2. Substitute the given values: Perimeter = 2(20) + 2(10) 3. Simplify the expression: Perimeter = 40 + 20 Perimeter = 60 feet So, the student needs to buy at least 60 feet of fencing to enclose the garden.
