Let's call the width of our rectangle
and the length
. We can say
, since the length is equal to 4 cm greater than the width.

. To solve this problem, we can substitute in the information we know, as shown below:




Now, we can substitute in the width we found into the formula for length, which is
:


The width of our rectangle is
cm and the length of our rectangle is
