To determine the number of bags of fertilizer Bob Bender needs to buy, we need to calculate the area of his square garden and divide it by the coverage area of one bag of fertilizer.
1. First, let's find the area of Bob Bender's square garden. Since the garden measures 10 feet on each side, the area is calculated by multiplying the length by the width:
Area = Length × Width = 10 feet × 10 feet = 100 square feet.
2. According to the instructions, one bag of fertilizer covers 50 square feet of soil.
3. To calculate the number of bags of fertilizer required, divide the area of Bob's garden by the coverage area of one bag of fertilizer:
Number of bags = Area ÷ Coverage area per bag
= 100 square feet ÷ 50 square feet per bag
= 2 bags.
Therefore, Bob Bender needs to buy 2 bags of fertilizer for his vegetable garden.
Now let's determine the amount of fencing Bob needs for his garden:
1. The perimeter of a square garden can be calculated by multiplying the length of one side by 4 (as a square has four equal sides). Therefore, the perimeter is:
Perimeter = 10 feet × 4
= 40 feet.
Therefore, Bob Bender needs to buy 40 feet of fencing for his vegetable garden.
