Question

A rectangular dog pen has an area of 108 square feet. The width of the pen is 9 feet. What is the length?

Answer 1

i got 6.
i did 9*9=18
18/108=6
9*6=54
54+54=108

Answer 2

A=area
w=width
l=length

A=w × l plug in the given values...
108=9 × l now divide both sides by 9, and you get....
12= l

so the missing length is 12.

Answer 3

student_basil is right.

As for GinjaTheNinja, the length would have had to be more than the width, so 6 doesn't make sense.

Answer 4

ohh thanks
