The length of a rectangular sports ground is 18 m, which is 2 times more than its width.

The length of a rectangular sports ground is 18 m, which is 2 times more than its width. How many steps do you need to take to get around the site if the step length is 60 cm.

Let a be the length of the site, b – the width of the site.

Then, by condition, a = 18 m, b = a / 2 = 18/2 = 9 m.

Since the site has the shape of a rectangle, its perimeter will be equal to:

P = 2 * (a + b) = 2 * (18 + 9) = 54 m.

Let’s determine how many steps you need to take:

X = 54 / 0.6 = 90 steps.

Answer: You need to take 90 steps.
