Length and width

Use the 5-step procedure. The perimeter of a rectangle is 34 in. The length is 4 in less than three times the width. Find the length and width.

Correct answer:

l =  11.75 in
w =  5.25 in

Step-by-step explanation:

p=34 in  p=2l+2w l=3w4 34=2l+2w l=3w4  34=2 l+2 w l=3 w4  2l+2w=34 l3w=4  Row221 Row1Row2 2l+2w=34 4w=21  w=421=5.25 l=2342w=2342 5.25=11.75  l=447=11.75 w=421=5.25
