A rectangular garden bed is 12.5 feet long and has an area of 100 square feet. What is the width of the garden bed, and how many square feet of space will be left if you need to leave a 2-foot border around the entire bed?"

• o find the width:
  • Area = Length x Width
  • 100 sq ft = 12.5 ft x Width
  • Width = 100 sq ft / 12.5 ft = 8 feet
• To find the area of the border:
  • Calculate the area of the entire garden with the border by adding 4 feet to each side: (12.5 ft + 4 ft) x (8 ft + 4 ft) = 210 sq ft
  • Subtract the original garden area: 210 sq ft - 100 sq ft = 110 sq ft of border space
