Krista’s mom has told her she need to make the pen 1
2 the size
that she had planned (5 feet long by 4 1
2 feet wide). What will the
area be? What are two possible lengths and widths she could use?
To make the pen half the size, the new dimensions would be 2.5 feet long by 2.25 feet wide.
The area of the original pen would be 5 feet x 4.5 feet = 22.5 square feet.
The area of the new pen would be 2.5 feet x 2.25 feet = 5.625 square feet.
Two possible lengths and widths she could use are:
- 5 feet x 4.5 feet
- 6 feet x 5 feet
