Question

The lengths of the four sides of a quadrilateral (in feet) are consecutive integers. If the perimeter is

86
86 feet, find the value of the longest of the four side lengths.

Answer 1

23

Explanation:

because consecutive integers, that means each one is longer than the previous one

length 1= x

length 2 = x+1

length 3 = x+2

length 4 = x+3

so 4x+6 =86

x = 20

longest =20+3 =23
