2:3:5:8= 360
2x+3x+5x+8x=360
18x=360
x=360/18
x=20
2x+1= 2×20+1 = 41

Step-by-step explanation:
let the sides be 2x , 3x , 5x and 8x respectively.
According to question,
= 2x +3x +5x+ 8x = 360
= 18x = 360
Therefore, x = 360 ÷18
= 20
Therefore , sides of the quadrilateral are
= 20×2 = 40
= 20×3 = 60
= 20×5 = 100
= 20×8 = 160
