Find the perimeter of a rectangular piece of land with an area of 97,200 m2 and one side 3 times larger than the other.

Let x meters be the width of the rectangular area;

Then 3 meters is the length of the rectangular section;

Let’s compose the equation of the area of the rectangle and find x:

3x * x = 97200 m²;

3x² = 97200;

х² = 97200/3;

x² = 32400;

x = 180 m – the width of the site;

3x = 3 * 180 = 540 m – section length;

The perimeter of a rectangle is equal to the sum of all its sides, just like the perimeter of any shape. Let’s find it:

P = a + b + c + d;

P = 180 + 540 + 180 + 540 = 1440 m – perimeter.

Answer: The perimeter of a rectangular land plot is 1440 meters.
