5/x=42/63. So 42x=315. And x=7.5 so the shadow is 7.5 ft long
Using the concept of similar triangles, the length of the shadow of the 5-foot girl is calculated to be 7.5 feet. This is derived from the proportional relationship between the height of the girl and the tree along with their corresponding shadows. Therefore, when the tree height is 42 feet and its shadow is 63 feet, the girl's shadow can be determined as 7.5 feet long.
