The side lengths of the quadrilateral are even consecutive numbers.

The side lengths of the quadrilateral are even consecutive numbers. Find the lengths of these sides if the perimeter of the quadrilateral is 228 cm.

Let the smallest side of a given quadrangle be x cm, then the rest are x + 2 cm, x + 4 cm, x + 6 cm.

Knowing that the perimeter of the quadrangle is 228 cm, we can write:

x + x + 2 + x + 4 + x + 6 = 228;

4 * x + 12 = 228;

4 * x = 228 – 12;

x = 216/4 = 54 cm.

Therefore, the sides of this quadrilateral are equal:

x = 54 cm,

x + 2 = 56 cm,

x + 4 = 58 cm,

x + 6 = 60 cm.
