Itzel Middleton · Answer 1

2L+2W=72

L=3W+4

2 (3w+4) + 2W=72

6w+8+2W=72

8+8W=72

-8 - 8

8W=64

W=8 L=28

Van Roberts · Answer 2

3x + 4 where x represents the width

P = 72 m

trial and error:

1. 3 (20) + 4 = 64

2. 3 (23) + 4 = 73

3. 3 (22.67) + 4 = 72.01 - - - round answer to nearest decimal place
