Question from Debourah, a student: a soccer field is 1080 square meters the width is 2 meters less than one-third the length. What are the dimensions of the field? |
Hi Debourah,
You need to very carefully read what the problem states. Suppose that the width of the field is W metres and the length is L metres, then you know that
L × W = 1080
Furthermore you are told something about the width W and one-third the length 1/3 L. You are told that W is 2 metres less than 1/3 L, that is
W = 1/3 L - 2
Substitute this value for W into the first equation. This will give you one equation in the variable L which you can then solve.
I hope this helps,
Penny
