A plot of rectangular shape, the width of which is 2 times shorter than the length, was sown with oats

A plot of rectangular shape, the width of which is 2 times shorter than the length, was sown with oats. The perimeter of the plot is 1140 m. what is its area?

We find the sum of the sides of the site.

Since the perimeter of a rectangle is twice the sum of its sides, the sum of the length and width of the section will be equal to:

1140/2 = 570 meters.

Let’s write down the width of the site as an unknown number x.

Since its length is 2 times its width, it will be: 2 * x.

We get the equation:

x + 2 * x = 570.

3 * x = 570.

x = 570/3 = 190 m (section width).

2 * x = 2 * 190 = 380 m (section length).

The area of the site will be equal to:

190 * 380 = 72,200 m2

Answer:

Land area 72,200 m2
