Question

The lengths of the four sides of a quadrilateral (in feet) are consecutive even integers. If the perimeter is 92 feet, find the value of the longest of the four side lengths.

Answer 1

The perimeter of the quadrilateral is the sum of the four side lengths. If the perimeter is 92 feet, then we can write the equation $x + (x+2) + (x+4) + (x+6) = 92$, where $x$ is the length of the shortest side. Solving this equation, we find that $x = 20$. This means that the side lengths are 20 feet, 22 feet, 24 feet, and 26 feet, so the longest side is 26 feet.
