The length of a rectangular piece of land is 15m, the length is three times less. Find the perimeter

It is known from the condition that the length of a rectangular piece of land is 15 meters, the length is three times less than the width. In order to find the perimeter of a rectangle, let’s first find the width of the rectangle.

We know that the length is three times less than the width, meaning the width is three times the length.

Let’s calculate the width:

15 * 3 = 45 meters width of the rectangle.

Let’s remember the formula for finding the perimeter of a rectangle.

P = 2 (a + b), where a and b are the length and width of the rectangle.

Substitute the values and calculate:

P = 2 (15 + 45) = 2 * 60 = 120 meters perimeter of the land.
