1-69.

Write one or two equations to help you solve the following problem.

A rectangle’s length is four times its width. The sum of its two adjacent sides is $22$ cm. How long is each side?

Draw and label a picture or make a table of values to get started.

 $w$ $\$ $4w$
 Width Length Sum $2$ $8$ $10$ $3$ $12$ $15$ $4$ $16$ $20$ $w$ $4w$ $5w$

$(4w)+w=22\\5w=22$
