Image not displaying proper

I have some lable content to display on screen. I used background image for label content. When it displays, the background image width is stoping when the text width is stop. See the below images. The elephant image label & background displays proper. But the cow image background image is stoping. why?

 GUI.skin.label = style;
             
              GUI.skin.label.margin.bottom = 80;
             
     GUILayout.Label(" Cattle are herbivores that eat vegetation such as grass\n\nCattle stomachs have four chambers which help break down what they eat         \n\nThere are well over 1 billion cattle in the world\n\nYoung cattle are generally known as calves\n\nAdult females are generally called cows\n\nCattle are red/green colour blind", style);
