| Let’s take the width of the rectangle as 100%.

Let’s find how many meters in 1% for this:

36: 100 = 0.36 (m).

Let’s determine how many meters is 35%:

0.36 * 35 = 12.6 (m) for so many meters the length of the rectangle is greater than the width.

Let’s find the length of the rectangle:

36 + 12.6 = 48.6 (m) the length of the rectangle.

Knowing the formula for the perimeter of the rectangle P = 2a + 2b, we calculate:

36 * 2 + 48.6 * 2 = 72 + 97.2 = 169.2 (m) perimeter.

Answer: 169.2 m. The perimeter of this rectangle.
