A. Your bed is a rectangle that is 4 feet by 6 feet wide. Draw a model of it below and label the dimensions. Find the perimeter
musickatia [10]

The model which model the dimensions of the bed has been attached.

  • The perimeter and area of the bed is 10 feet and 24 square feet respectively.
  • The perimeter of your bed is less than the perimeter of the items, so not all items can be underneath your bed.

<h3>What is the perimeter and area of the bed?</h3>

  • Length of the rectangle = 6 feet
  • Width of the rectangle = 4 feet

Perimeter of the bed = 2(length + width)

= 2(6 + 4)

= 2(10)

= 20 feet

Area of the bed = Length × width

= 6 feet × 4 feet

= 24 square feet

  • Perimeter of the suitcase = 14 feet
  • Perimeter of Lego box = 10 feet
  • Perimeter of memory box = 10 feet
  • Perimeter of stash = 6 feet

Total perimeter = 14 + 10 + 10 + 6

= 40 feet

Therefore, the items listed can not all be underneath your bed because the total perimeter of the items is greater than the perimeter of your bed.
