Answer:
6 units
Step-by-step explanation:
There are 5 sides in a pentagon. If the shortest side is x, then the other 4 sides are x+2, x+4, x+6, and x+8.
The perimeter is therefore:
P = x + x+2 + x+4 + x+6 + x+8
P = 5x + 20
The second longest side (x+6) is 24% of the perimeter.
x + 6 = 0.24 (5x + 20)
x + 6 = 1.2x + 4.8
1.2 = 0.2 x
x = 6
The length of the shortest side is 6 units.
