Answer:
140 m
Step-by-step explanation:
The length of the rectangular deck on the layout is 4 cm and the width is 3 cm.
Find the perimeter of the layout deck:
[tex]P_{\text{layout deck}}=2\text{Length}+2\text{Width}=2\cdot 4+2\cdot 3=8+6=14\ cm[/tex]
You know that 1 centimeter = 10 meters.
To find the perimeter of Mark's deck, just multiply the number of centimeters the perimeter of layout deck consists of by 10:
[tex]P_{\text{Mark's deck}}=14\cdot 10=140\ m[/tex]
