The length of the rectangular platform is 18 meters and the width is 9 meters. How many steps must be taken to get around it if the step length is 75 cm.
In order to bypass the site, you must walk a path equal to the perimeter of the site.
The perimeter of the rectangular area will be P = 2 * (a + b), where a is the length of the area, b is its width.
Let’s find the perimeter of this site:
P = 2 * (18 + 9) = 2 * 27 = 54 (m).
The step length is 75 cm or 0.75 m.Let’s find how many steps make up the perimeter of the site:
54: 0.75 = 72.
Answer: 72 steps.
