Eduardo is building a sandbox that has an area of 84 square feet. What are the possible whole number measurements for the length and width of the sandbox?
To find the area, of a rectangle, you multiply length by width. Therefore, any factor pairs of 84 would be possible measurements for the length and width of the sandbox. length=1ft, width=84ft (1x84=84) length=2ft; width=42ft (2x42=84) length=3ft; width=28ft (3x28=84) length=4ft; width=21ft (4x21=84) length=6ft; width=14ft (6x14=84) length=7ft; width=12ft (7x12=84) And switching the numbers around gives you more possibilities. length=12ft; width=7ft length=14ft; width=6ft length=21ft; width=4ft length=28ft; width=3ft length=42ft; width=2ft length=84ft; width=1ft 12 total possible whole number pairs for the length and width of the sandbox. See how that works? Easy as pie, so long as you have the patience to find all the factors. I hope this helps!
